306 multiple charsets and thus has no hope of working properly under Mule.

307 What we really should do is create a collation table over all built-in

308 charsets. This is extremely difficult to do from scratch, however.

131b0175ea99 Import from CVS: tag r20-0b30

311 it is quite likely that a collation table exists (or will exist) for

312 Unicode. When Unicode support is added to XEmacs/Mule, this problem

313 may be solved.
