Thank you everyone for your advice. Some kinds of names are restricted to unicode alphabetic/numeric in Rust. And the current definition of the table defined in libcpp/ucind.h lacks some rows representing which characters are alphabetic/numeric. But it is not a problem because it seems to be easy to add missing rows to the table and use it in the Rust frontend.

Yes, NFC normalization must be done by the lexer, which may be complex and hard to implement. libunistring can also be used for normalization, so is it good to use libunistring only in the normalization process?
