One thing I noticed is that "collations" != "case change". This will not make it possible to use UPPER/LOWER with the same data on the table, but maybe we can work on something in that respect, also.
If the intent is case-insensitive comparisons a la LIKE, note that "upper" and "lower" operations alone won't suffice, because in some scripts a single character maps to multiple characters in one direction. Unicode defines a "case folding" operation for such uses, which does full expansion no matter which direction it is (lower->upper or upper->lower), allowing the result to be handled with a simple memcmp()-style binary comparison. It should certainly be possible to cover those operations too, it's just as nuanced as the collation work :) ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
