Martin,
The standard upper to lower case conversion makes huge assumptions and
is very Western character set targeted. For example ... many people and
many simple functions assume that converting a character from upper to
lower case will give you the same size of character [or same length of
string] which is simply not true.
The Unicode library I posted has full support for Unicode upper to lower
and lower to upper case conversion and these features are easy to use.
Yours,
Graham
