All good questions. To back up for a moment, my original plan had been to wait longer and see if we could get a better version of that patch accepted into gnulib. However, we're accelerated from that now because us using an old gnulib is holding up other efforts (and according to my bug mail this morning, is needed to build with newer gcc/glibc). > How was this patch functionally being used by GRUB?

Mostly it seems to change gnulib's width assumption to be multibyte-character aware. I think this could cause lines to not wrap early in locales that are mutibyte-heavy, but I don't actually know, as I don't speak any languages that meet that criteria. gnulib upstream pointed out that this is only papering over the problem though: it won't work for Chinese, for instance. (It also won't work for Thai, but there's nothing that anyone can do there.) I could be wrong, but I'm actually not sure this affects grub at all. We're not translated, which I think means that every character we put in a help string will fit in a single byte under UTF-8. Be well, --Robbie
