NAME
     unicode::tolower,	unicode::toupper,  unicode::totitle - unicode version of
     tolower(3) and toupper(3) and totitle(3) (if there was such a thing)

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::u32string unicode::tolower(const std::u32string_view &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_view &u);

     std::string unicode::totitle(const std::string &string);

     std::string		     unicode::totitle(const std::string &string,
				  const std::string &charset);

     std::u32string unicode::totitle(const std::u32string_view &u);

DESCRIPTION
     These  functions  convert	the  string parameter, in charset or unicode_de-
     fault_chset(3), to unicode, replace each character with  unicode_lc(3),  or
     unicode_uc(3)  or unicode_tc(3), then convert it back to the same character
     set, returning the resulting string.

     Passing a const std::u32string_view & directly  also  converts  it  accord-
     ingly, returning the converted unicode string.

SEE ALSO
     courier-unicode(7).
