ICU: What does NFD and NFC mean?

我找到了一个片段，上面写着

Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC; [:Punctuation:] Remove; Lower();

...并且应该使任意字符串很好地适合 URL。

所以，我猜分号之间的东西类似于"commands"，它们将被执行，但是NDF和NFC具体代表什么？我真的在官方文档中什么也没找到...

有关完整示例，请参阅 ICU transliterators and the linked page on TR15 normalization forms。
