But it's a name, an identifier. It's like saying "*" can suddenly be a 
part of a C variable name.

Besides, there are special cases to consider - what about names 
containing successive slashes and possibly C escape sequences? I say - 
sanitize it completely, leave either 7-bit ASCII or UTF-8 (but in both 
cases strip slashes and characters < 0x20).
