在v2ex里发现的，原来竟然有这么个字符

上面这些也有。

LZ 可以点 编辑, 特殊字符... 看看。

u'\uf8ff'据说不是专门给apple的,而且各个系统自己可以设置.

@bitsmix 你这些我早见过啦，没cool呀，哈哈

只有苹果设备能看见。

In Unicode, Private Use is a concept to allow characters to be defined and used by private agreement between parties (that is, not involving the Unicode Consortium), using unspecified code points in a Private Use Area or range. The private agreement may be published, and often is. Such publication may include a font that supports the definition (showing the glyphs), and processes to support privately-defined graphic or even control effects (e.g. a clickable <do print> character). As a stability rule, the Unicode Standard guarantees these Private Use code points will never be assigned regular characters, so Unicode will never interfere with the private agreement.
For example, Apple Inc. has published the Apple logo to be encoded at Private-use code point U+F8FF <private-use-F8FF>, and maintains this in its fonts and systems.
By definition, multiple private parties may define a specific code point this way, with the consequence that a user can experience using the wrong font, seeing characters from another definition set.

楼主，无根据的瞎猜是会招来嘲笑的

In Wingdings 1, is the Windows logo. In some computers, however, it is (U+F000) instead of .

win下看见的全是 口 *_*

win下看见的全是 口 *_*

@blacktulip 受教了，原来是苹果自定义的，:)

@luofei 我的win下比口还难看，是口里面写着F8FF，F8在上，FF在下

@tuoxie007 每个字体可以定义找不到某个字符的时候统一用一个符号代替，也许你换过字体？win默认的字体应该是一个口

@tuoxie007 Windows里面如果没有对应字符的话就会显示一个含有4位16进制值的方块

@kelvinsze 没改过字体，我这里firefox里看到的不能显示的字符都是这样的呢

@skydiver 对嘛，就是口里面就是F8FF，就是这个u'\uf8ff'么

为什么在ubuntu下面也是苹果？

@21grams：什么字体？
