unicode::tolower3
Unicode version of tolower(3) and toupper(3)
Usage
#include <courier-unicode.h>
std::string unicode::tolower(const std::string &string);
std::string unicode::tolower(const std::string &string, const std::string &charset);
std::u32string unicode::tolower(const std::u32string &u);
std::string unicode::toupper(const std::string &string);
std::string unicode::toupper(const std::string &string, const std::string &charset);
std::u32string unicode::toupper(const std::u32string &u);
Overview
These functions convert the string parameter, in charset or unicode_default_chset(3), to unicode, replace each character with unicode_lc(3) or unicode_uc(3), then convert it back to the same character set, returning the resulting string.
Passing a const std::u32string & directly also converts it accordingly, returning the converted unicode string.
