It certainly doesn't seem like a big problem at first glance. But, in
networking, it is sometimes bad to have too much flexibility. It has a
way of coming back to haunt you later.

Actually, the Unicode database does contain some info that we might be
able to use in Nameprep. Double-struck C has the tag <font> in its
Character Decomposition Mapping, while the Japanese wide characters have
the tag <wide>. So Nameprep could choose to normalize just the <wide>
characters and maybe some of the others, but not <font>. For domain
names, that may be the way to go.
