If this is not what you wanted, you will simply have to write a longer = post.
=20

CJK =3D (I think) Chinese, Japanese, Korean. "CJK characters" usually
refers to the encodings you use for those - Big5, JIS, Unicode, etc.

You may need to use the Oniguruma patch. I believe this is necessary
to give regular expressions support for character sets other than
plain ASCII.

http://www.geocities.jp/kosako3/oniguruma/

If you're using Gentoo, all you need to do is remerge Ruby with the
cjk use flag turned on. For other systems, you may need to download
and apply the patch manually. See the Oniguruma site for more details.
If you're using a 1.9 Ruby, Oniguruma is already built-in.

Regular expression comes with 1.8 does support UTF-8.

Regular expression comes with 1.8 does support UTF-8.

does this mean though that you must do a match on an escaped character
(\u1234 or on a 'real' character?)

You don't have to escape, if you specify -Ku or $KCODE='u'.
