Hi Michael, I don't understand what this paragraph means, I think it needs some wfix. Around setlocale.3:179: [ On startup of the main program, the portable "C" locale is selected as default. A program may be made portable to all locales by calling: setlocale(LC_ALL, ""); after program initialization, by using the values returned from a localeconv(3) call for locale-dependent information, by using the multibyte and wide character functions for text processing if MB_CUR_MAX > 1, and by using strcoll(3), wc‐ scoll(3) or strxfrm(3), wcsxfrm(3) to compare strings. <<<Especially these last 2 lines ] Thanks, Alex -- Alejandro Colomar Linux man-pages comaintainer; https://www.kernel.org/doc/man-pages/ http://www.alejandro-colomar.es/
