For clarification: I am unsure just how well Ruby's regexp engine
handles Unicode "extended latin" characters, a trivial test using $KCODE
=3D 'u', require 'jcode', and iconv failed for me. But that could be me
getting the codepages wrong. The above is just saying that there is
nothing saying that a regexp engine properly supporting Unicode and
character classes would be unsuitable to validate non-ASCII text.
