However it will be weird, especially from me as a user POV. There is no default collation/ctype (locale) for an encoding, only the other way around. So if a user picks as locale, let's say, de_DE@euro, then the encoding is automatically LATIN9 (obsolete), if the locale is de_DE.utf8, then the encoding is UTF8, and so on.
