Comment 4 for bug 666565

Yes, changing is risky. An alternative option is "fix" this in langpack-locale, and try to make everywhere in the system to use "utf8" if any problems occur. A temporary solution to use both utf8 and UTF-8 is of course needed, and it should be just a work around. Such problem tends to cost more and more time to fix issues when users need to change locale settings, and the complexity of dealing related problems are now much higher than ever before.
