Of course you don't.  21.5 can read Unicode Consortium-style mapping
files and create a chartable from that.

Regarding bugs in CCL, what it comes down to is that there is
currently *one* person asking for improvements in it and *no*
volunteers.  (Maybe Aidan will do it; he has different tastes about
CCL from me---but he hasn't said he will yet, and there are other
things I hope he'll do first.)

If necessary the change the Aidan introduced to 21.4 can be reverted.
Would that fix your immediate problem?
