I am not sure about how promptly it'll be fixed in glibc, as this may require more developer oomph in the localedata area. Although Bruno Haible did a nice analysis of the issue <https://sourceware.org/bugzilla/show_bug.cgi?id=19932> he had some qualms about changing this part of glibc, and anyway I expect he has few free cycles to think about this. And to be honest, fiddling with localedata is not my fave....
Since the problem has apparently been in glibc for a decade and a half, I'm a bit surprised nobody filed a bug report about this until now. Perhaps it's because apps that care about i18n and text processing (e.g., Emacs, Firefox) largely bypass mbrtowc and do all the decoding themselves?
