The only problem is that it should consider multi-codepoint
replacements aka full-case folding in Unicode.
Otherwise - go ahead and issue a pull request to add
special case for < 0x80.
In case someone wonders, an example for multi-codepoint
replacements is when ß becomes SS in upper-case.
What about locale dependent case mappings (e.g. Turkish Iı İi)?
Or is that currently not supported by std.uni?
I second those thoughts. Important players* agree that you
cannot do case conversion or string sorting without knowing
the locale and sorting scheme, and Phobos that set out to be
"Unicode first" can't even express locales to begin with.
Proper handling of that is called tailoring in Unicode. Personally I
don't think it would be terribly hard to go and do:
Locale locale = fetchSomeTailoredLocale(...);
locale.toLower(...); // etc. all functions as members
By the way we do what is called default handling (tables) which is
sensible "default" IMO.
