I perfectly agree. (Actually, i think that U+7F (delete) and the C1 control characters
should be excluded [transformed into U+FFFD] as well, but this could perhaps be
problematic due to spurious CP1252 characters.)

Hopefully, very few pages rely on C0 control characters or the explicitly undefined
U+FFFE and U+FFFF.

Actually, this comment pertained to the intention behind the definition of NCName
in XML 1.0, implying that at least the intention was not completely arbitrary.
