Personally, I consider that users setting locale variables other than LC_CTYPE and LC_MESSAGES mean literally "please break random programs on my system"; I am convinced of this since more than fifteen years when initing Gtk in the OCaml toplevel would cause "let pi = 3.14" to set pi to 3.0. Therefore, my opinion on this is: let us document that for all FFmpeg libraries, setting any locale except these two to anything other than C/POSIX yields undefined behaviours. If people want to write applications using various locales, they should use the version with explicit locale argument introduced in the latest version of the standard. Regards, -- Nicolas George
