Another question: Do you know of any cases where a "case neutral"
representation from equivalent upper and lower cases?
I know you are familiar with the famous Knuth article on collation.
I don't think we need to collate "1812 Overture" as the letters
forming the German words to 1812, but leaving room clearly useful
non-English equivalents is important.
Does the collation driver mechanism currently support case changing?
If so, can a single pair of entrypoints (upcase, downcase) suffice.
If the French want separate ACCENT/NOACCENT collating sequence, can
we reasonable expect them to support two different drivers?
How much trouble are we getting ourselves into?
