Re: [idn] nameprep2 and the slash homograph issue

I guess you could make the case that U+2215 is different from national 
characters, because it is a mathematical operator. Similarly, U+2044 is 
a general punctuation character. Are either of these already banned by 
nameprep?

There is another character U+30CE that looks like a slash. Perhaps we 
would warn about characters like this in nameprep2?

I still wonder whether U+2215 and U+2044 are sufficiently problematic to 
require a new ACE prefix.
