In the GNU library glibc 2.2, is it true to say that all wide character C functions are based on UTF-32 (since their character arguments are wchar_t) and properly handle such character encoding according to the Locale (assuming setlocale(LC_ALL,"") has been called). If true, it means that my application can use these wide character C functions to process Unicode character data to correctly process Unicode character data according to the Locale.
But, is it also true to say that under Linux utf-8 Locales, all C functions handle properly char data representing utf-8 character encoded data? Do strlen, strchr, strcmp, strcpy, toupper process char data correctly when the Locale character encoding is utf-8? OR I need to use the wide character functions after specific conversion from char to wchar_t of my charatcer data? Which functions (wide and non wide character) correctly handle utf-8 data and which ones do not? And what is the recommended option if I want to developped a fully i18ned application (use the utf-8 Locale support; or convert internally to utf-32 by using wchar_t and wide character functions; or use ICU).
