NAME
unicode::tolower, unicode::toupper - unicode version of tolower(3) and toupper(3)
SYNOPSIS
#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::vector<unicode_char> unicode::tolower(const std::vector<unicode_char> &u);
std::string unicode::toupper(const std::string &string);
std::string unicode::toupper(const std::string &string, const std::string &charset);
std::vector<unicode_char> unicode::toupper(const std::vector<unicode_char> &u);
DESCRIPTION
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::vector<unicode_char> & directly also converts it accordingly, returning the
converted unicode string.
