Ava is the young daughter of the brilliant-but-aging scientist Dr. Cavor and Selene, the former queen of the moon. As a selenite, Selene's life depends on the special energy only moon gems can provide. With none left and time running out, Dr. Cavor enlists his daughter to raid the moon.

Please avoid using it on the web
Some people have noticed, and begun using, the unicode values for theApple Logo.- The only area where I wish it could perform magic is if the app could detect whether I'm in a remote session client app (like Mac's Screen Sharing) and then ignore the keystrokes and pass them through to Moom in the remote Mac OS session. For now I just use the mouse-over on the window's green button in the remote mac sessions. 😊 Mojave Review.
- The moon moves through a regular 29.53 day cycle. During which it appears to become either smaller or larger due to the relative position between the earth, moon and sun. The larger the angle distance between the moon and the sun., the more of the moon we see illuminated.
- Moon Phases Noren Curtain, Lunar Moon Doorway Curtain, Japanese Wall Tapestry Door Way Curtain Decor, Room Dorm Division, 33.5'x55' 85x140cm RomanticTasteStudio 4.5 out of 5 stars (4).
This is probably fine for Mac-only applications. But it is NOTappropriate,and even WRONG, and it will NOT work properly as a generalweb page character.The problem is that the unicode value used is one of several that is setaside for private use. That means that each operating system, orapplication, or implementation is free to use those unicode characters foranything they want. It just so happens that Apple has chosen to useunicode character U+F8FF (decimal value 63743, or on the web as either or ) as the Apple Logo.But some Windows fonts put in a Windows logo. And some other fontsput in a Klingon Mummification glyph. Or elven script. Or anythingthey want. And if it isn't defined in yourlocal font, you'll just see a square. So who knows what you mightsee when I put the character in right here:
Yes, on a Mac, you probably see an actual Apple Logo. But on othersystems, you probably see other things. So what is it good for? Youcan use it on Mac-only programs, and it'll probably work fine (especiallyif the application explicitly sets the font to one where you know thischaracter is defined as the Apple Logo). You can even use it on Mac-only web pagesif you are absolutely sure that you don't care if it is wrong on non-Macbrowsers.
But you can not claim surprise when people say they see a Windows Logo onyour Apple web-page.
Slightly More Useful Mac characters
Unicode does define some other characters which are sort of Mac-specific.⌘ - ⌘ - ⌘ - the Command Key symbol
⌥ - ⌥ - ⌥ - the Option Key symbol
⇧ - ⇧ - ⇧ - the Shift Key (really just an outline up-arrow, not Mac-specific)
⎋ - ⎋ - ⎋ - the Escape Key (also not Mac-specific; described as 'BROKEN CIRCLE WITH NORTHWEST ARROW', or an escape character from ISO 9995-7). I originally thought this was supposed to be a symbol for the power button.
And while we're at it, some related (not mac-specific):
⇥ - ⇥ - ⇥ - the Tab Key symbol
⏎ - ⏎ - ⏎ - the Return Key symbol
⌫ - ⌫ - ⌫ - the Delete Key symbol
⌽ - ⌽ - ⌽ - a possible substitute for the Power symbol
Even though these are defined in standard Unicode, there is no guaranteethat they will exist in the font of the receiving browser, but they're at leastglobally defined, so they're fair game.
Peeve
And as long as we're on the subject, it's a peeve of mine how pedanticsome people get about unicode. There is no proper power button symbol inUnicode.Some pedantic unicode people claim it hasno place in Unicode, but it would just be entirely too useful indocumentation. And of courseUnicode is littered with an arbitrary set of cute little pictures, most ofwhich are far less useful, but theywon't put in standard things like this. An even better example would be thelack of audio-visual symbols, such as play, stop, and pause symbols. You cantry to cobble these things together from some of the geometric shapes andblock symbols, but even if you manage an adequate look in one font, inanother these same shapes may look completely unmatched and innappropriate.Feh.
Update: December 2010As of October, Unicode 6.0 is out, and it adds lots of new stuff (notethat very few fonts actually support these yet). New stuff likeemoticons. Map symbols.There's a bomb symbol. There's bicycles (and lots of other transportsymbols). Thumbs up and down, and an 'ok' sign (but no flipping the birdthat I could find). Animal symbols.
They also added some audio symbols. There's symbols for mute, unumute, volumeup/down (and brightness up/down). Theres a single play/pause symbolnow. And there's fast forward, and rewind. There's skip forward andback if you like double arrow and vertical bar, but not if you onlywantd a single arrow and vertical bar.
BUT there is still no pause symbol! This is hard to imagine. Thereare several different single vertical bars that can be paired up. But Ihave not found one which always pairs appropriately in all fonts. It'sinsane that they left this out. Maybe it's there and I haven't found ityet? Please?
And the same for the power symbol. A kind reader pointed out thatat least in some fonts, the U-233D 'APL Functional Symbol Circle Stile'symbol - ⌽ - looks like the IEC 5010 power symbol (a vertical lineinside of a circle). Climb the rooms mac os. The official code charts example shows it as a verticalline going through a circle not inside of it. And at any rate, most'power' buttons are soft buttons and appropriately use the IEC 5009standby symbol, which is a vertical line entering the top of an opencircle. This does not exist at all as far as I can tell.
So, nice try, but no cigar.
Update: November 2014Apparently Unicode is making progress. Sometime in 2014, they added in a'double vertical bar' symbol (U+23F8), which is commented as the pause. They also added play, stop, record, and a few others in a dedicated block. Some of them are explicitly named for there function but most are named for their appearance, with the function listed only as a comment. This is fairly typical. Designers of fonts should use the comments to understand a symbol's real, practical (current) usage, so they can making the 'double vertical bar' look appropriate for pause, just as they should make that new 'black waning crescent moon' symbol look appropriately like the standard 'sleep' icon.
Also, they've supposedly voted in a few power-related symbols,including a 'power' symbol (U+23FB) which is the IEC 5009 symbol, as well as a sleep symbol (U+23FE), and a dedicated 'toggle power' symbol (U+23FC). However these still don't appear in their official code charts. Unicode.orglists theseas in 'stage 6', 'accelerated for publication in the Unicode Standard while still in active technical ballot'. They'll probably be in Unicode 9.0.
Coincidentally, all the things I whined about here are all in the U_23Fx range. It's like I have my own little dedicted block there in Unicode. Whining wins.

If it just so happens that lots of font designers all put these glyphs in these slots, how can that be wrong? |

December 2010
Please avoid using it on the web
Some people have noticed, and begun using, the unicode values for theApple Logo.This is probably fine for Mac-only applications. But it is NOTappropriate,and even WRONG, and it will NOT work properly as a generalweb page character.The problem is that the unicode value used is one of several that is setaside for private use. That means that each operating system, orapplication, or implementation is free to use those unicode characters foranything they want. It just so happens that Apple has chosen to useunicode character U+F8FF (decimal value 63743, or on the web as either or ) as the Apple Logo.But some Windows fonts put in a Windows logo. And some other fontsput in a Klingon Mummification glyph. Or elven script. Or anythingthey want. And if it isn't defined in yourlocal font, you'll just see a square. So who knows what you mightsee when I put the character in right here:
Yes, on a Mac, you probably see an actual Apple Logo. But on othersystems, you probably see other things. So what is it good for? Youcan use it on Mac-only programs, and it'll probably work fine (especiallyif the application explicitly sets the font to one where you know thischaracter is defined as the Apple Logo). You can even use it on Mac-only web pagesif you are absolutely sure that you don't care if it is wrong on non-Macbrowsers.
But you can not claim surprise when people say they see a Windows Logo onyour Apple web-page.
Slightly More Useful Mac characters
Unicode does define some other characters which are sort of Mac-specific.⌘ - ⌘ - ⌘ - the Command Key symbol
⌥ - ⌥ - ⌥ - the Option Key symbol
⇧ - ⇧ - ⇧ - the Shift Key (really just an outline up-arrow, not Mac-specific)
⎋ - ⎋ - ⎋ - the Escape Key (also not Mac-specific; described as 'BROKEN CIRCLE WITH NORTHWEST ARROW', or an escape character from ISO 9995-7). I originally thought this was supposed to be a symbol for the power button.
And while we're at it, some related (not mac-specific):
⇥ - ⇥ - ⇥ - the Tab Key symbol
⏎ - ⏎ - ⏎ - the Return Key symbol
⌫ - ⌫ - ⌫ - the Delete Key symbol
⌽ - ⌽ - ⌽ - a possible substitute for the Power symbol
Even though these are defined in standard Unicode, there is no guaranteethat they will exist in the font of the receiving browser, but they're at leastglobally defined, so they're fair game.
Peeve
And as long as we're on the subject, it's a peeve of mine how pedanticsome people get about unicode. There is no proper power button symbol inUnicode.Some pedantic unicode people claim it hasno place in Unicode, but it would just be entirely too useful indocumentation. And of courseUnicode is littered with an arbitrary set of cute little pictures, most ofwhich are far less useful, but theywon't put in standard things like this. An even better example would be thelack of audio-visual symbols, such as play, stop, and pause symbols. You cantry to cobble these things together from some of the geometric shapes andblock symbols, but even if you manage an adequate look in one font, inanother these same shapes may look completely unmatched and innappropriate.Feh.
Update: December 2010As of October, Unicode 6.0 is out, and it adds lots of new stuff (notethat very few fonts actually support these yet). New stuff likeemoticons. Map symbols.There's a bomb symbol. There's bicycles (and lots of other transportsymbols). Thumbs up and down, and an 'ok' sign (but no flipping the birdthat I could find). Animal symbols.
They also added some audio symbols. There's symbols for mute, unumute, volumeup/down (and brightness up/down). Theres a single play/pause symbolnow. And there's fast forward, and rewind. There's skip forward andback if you like double arrow and vertical bar, but not if you onlywantd a single arrow and vertical bar.
BUT there is still no pause symbol! This is hard to imagine. Thereare several different single vertical bars that can be paired up. But Ihave not found one which always pairs appropriately in all fonts. It'sinsane that they left this out. Maybe it's there and I haven't found ityet? Please?
And the same for the power symbol. A kind reader pointed out thatat least in some fonts, the U-233D 'APL Functional Symbol Circle Stile'symbol - ⌽ - looks like the IEC 5010 power symbol (a vertical lineinside of a circle). The official code charts example shows it as a verticalline going through a circle not inside of it. And at any rate, most'power' buttons are soft buttons and appropriately use the IEC 5009standby symbol, which is a vertical line entering the top of an opencircle. This does not exist at all as far as I can tell.
So, nice try, but no cigar.
Update: November 2014Apparently Unicode is making progress. Sometime in 2014, they added in a'double vertical bar' symbol (U+23F8), which is commented as the pause. They also added play, stop, record, and a few others in a dedicated block. Some of them are explicitly named for there function but most are named for their appearance, with the function listed only as a comment. This is fairly typical. Designers of fonts should use the comments to understand a symbol's real, practical (current) usage, so they can making the 'double vertical bar' look appropriate for pause, just as they should make that new 'black waning crescent moon' symbol look appropriately like the standard 'sleep' icon.
Also, they've supposedly voted in a few power-related symbols,including a 'power' symbol (U+23FB) which is the IEC 5009 symbol, as well as a sleep symbol (U+23FE), and a dedicated 'toggle power' symbol (U+23FC). However these still don't appear in their official code charts. Unicode.orglists theseas in 'stage 6', 'accelerated for publication in the Unicode Standard while still in active technical ballot'. They'll probably be in Unicode 9.0.
Coincidentally, all the things I whined about here are all in the U_23Fx range. It's like I have my own little dedicted block there in Unicode. Whining wins.

I think both browsers are using their default font configuration (but maybe I changed Firefox and can't remember :)). The Broken Circle with Northwest Arrow is the most strange. In Firefox it turns into an *un*broken circle with a diagonal line (not an arrow) through it. I totally agree with your peeve section. Unicode has so much esoteric cruft in it that squandared the code points, yet is missing several things which would be widely useful. It's not just the silly pictures (like the palm tree on a beach glyph) but things like dead languages which are only used by a handful of scholars. I imagine the 10 people who care about mixing Ancient Aramaic with other languages could get by using a special font and the private character ranges. As a programmer, it really annoys me because UTF-16 ran out of its 65,000 characters and now has some characters which are double-width (i.e. 32-bit), which leads to all kinds of bugs and security exploits due to code which doesn't handle such characters properly, either because the author didn't know or because they tried but it's ridiculously complex to deal with character strings where the characters use a varying number of bytes, and even more so when it's a very abnormal (i.e. rarely tested) case (unlike UTF-8). Sigh! |

I meant Meroitic: Existed for about 100 years and is currently spoken by zero people, yet it's taking up space in Unicode that is too valuable for music-playback symbols (etc.) which would only be useful to a few million people. :) (BTW, the posting form seemed to strip out the close-anchor tag if it used a lowercase 'a'. Using an uppercase 'A' made it work.) |

I would guess the reason that Apple uses 'BROKEN CIRCLE WITH NORTHWEST ARROW' instead of [ESC] is internationalization. Or to prevent people reading it as E+S+C. Or maybe just because key shortcuts are always shown with symbols. For the shift key, you might want to use 'UPWARDS WHITE ARROW' and for caps lock, the matching 'UPWARDS WHITE ARROW FROM BAR.' That is what Apple appears to be using in the Mac OS menus also. |
