While character classes like "%g" would require the entire Unicode
tables, what about patterns like this:

    utf8.match("\u{e4}", "[\u{e4}-\u{e6}\u{f3}-\u{f5}]")

It wouldn't require Unicode tables but "just" UTF-8 support for the
matching functions.

Would that be possible without adding too much bloat? When I had to
match codepoint ranges before, I had to use multiple patterns to match
certain ranges of UTF-8 encodings.
