WG1 - Strings and Chars

    
description

    
R6RS provided operations to alter the case
of strings and characters (upcase, downcase, titlecase
and foldcase) using locale-independent Unicode
mappings.  Do we provide equivalent mappings,
and how do they behave in the different char sets
we may allow per ticket #23?

I recommend that we provide these.  The character procedures should use Unicode simple mapping and folding (which is 1-1).  The string procedures should use Unicode full mapping and folding, which is usually 1-1 but sometimes not: "ß" upcases to "SS" and folds to "ss".

If the proper character is not supported by the implementation, the procedures should leave it alone: some Unicode lowercase characters have no uppercase equivalents, but coherent subsets of Unicode will usually provide both lower and upper case versions of all characters.
