That's an inherently unportable thing.

On native Windows, with the (lots of!) Gnulib overrides, with the MSVC compiler the locale French_France.65001 is a UTF-8 locale. But with mingw this does not work; probably something in mingw's setlocale() works differently than in MSVC's setlocale(). In summary: On mingw there is no UTF-8 locale, and you cannot force it. The only portable way out is to use iconv() instead of setlocale(), mbrtowc(), etc. This is how e.g. gettext's PO parser does it: https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=blob;f=gettext-tools/src/po-lex.c;h=22d08849206b812b18ace9de7629bb95a9d71c3c;hb=c9af3e4eeccc178a0833754e3d8c7083591e75ba lines 127..595. You will also find a function mb_width in there. Note that switching from locales to hand-written encoding support is a major change; I wouldn't recommend to do it before Texinfo 7.1. Bruno
