composite.el uses `general-category' and `canonical-combining-class'.
ucs-normalize.el uses `decomposition' and `canonical-combining-class'.
mule-cmds.el uses `name' and `old-name' for read-char-by-name.

Why did you have to create another table?  Was it because
get-char-code-property is defiend by Lisp and not efficient
to call from C?
