The CJKCompatibility block covers the codepoint range x3300-x33FF only. I
would imagine that to match Japanese language characters you are looking for
a much larger range than this.

If the range of codepoints you want to match doesn't correspond to one of
the named blocks you can always write, for example [&_#x3000;-&_#xFE4F;]
(without the underscores).
