Because it's not a Unicode character.  But actually Perl doesn't forbid
it consistently.  If you turn off warnings then codepoints are mostly
accepted without discrimination.  Perl has several sets of codepoints
that are frowned upon, and applies different sets in different situations.
I made a table of them some time ago, but I can't find it now.
