Unicode中编码为57344到57368的奇怪的符号是什么？

Unicode range E000–F8FF is used as Private use area which is reserved for private use. Unicode and ISO/IEC 10646 do not assign characters to any of the code points in this range. The repertoire seen with your computer's font will most likely not be the same as with other computers or fonts.

简略翻译：这部分是个人使用的，标准没有为这部分代码分配字符，而且不同字体显示不同。

另外在windows字符映射表里面这部分字符叫做"专用".如果你真想看，去

挨个看吧，这些东西MS是没有名字的
