Hello Unicode Folks,

U+01C3 looks like an 'Exclamation Mark' and it is categorized as 'Letter Other'.
U+02D0 looks like two inverted triangles and it is categorized as 'Letter Modifier'.

These code points being categorized as they are would not prevent them in an IDN. However, similar looking code points which are categorized as symbols or punctuation marks (U+0021 and U+003A) would be disallowed in an IDN (IDNA 2008).

My question is:

Should the code points be categorized differently so that they are disallowed by IDNA2008 RFCs, or
Should the individual end user applications prevent such kind of characters in an IDN.

Thank you.
