Python、unicodedata 名称和代码点值，我缺少什么？

Question

我正在处理 unicode 数据字符，我想知道为什么有些在 unicodedata 中没有任何名称？这是一个示例代码，您可以在其中检查 < unknown >

我认为 unicode 数据库中的每个字符都被命名了，顺便说一句，所有这些都是相同的类别，即 [Cc] Other, Control .

另一个问题:如何获取unicode代码点值？是ord(unicodechar)就这样了吗？

我也把文件here (因为编码是一件很奇怪的事情)，并且因为我认为我用“不可见”字符剪切和粘贴可能有损。

I thought that every characters inside unicode database were named

不，控制字符没有名字，参见UnicodeData文件

Another question: how can I get the unicode code point value? Is it ord(unicodechar) that does the trick?

是的!

print '%x' % ord(unicodedata.lookup('LATIN LETTER SMALL CAPITAL Z'))
