I started looking around the Unicode-related code, since I am planning
on applying to GSoC to work on Unicode improvements, and I found a bug
in digit-char-p. Specifically, there was a cond branch for non-ASCII
digits, but it was being skipped for radixes <= 10. I've attached a
patch that fixes the bug and adds test cases to catch it if it comes
back. Could someone give me some more information about code freeze, and
whether my patch is important enough to go through anyhow?

Also, who is generally the right person to talk to about Unicode issues?
