if we're loading a proper charset, then we load only the first set of chars, we can recolour the rest anyway (com_parseutf8 will do so anyway).

as a final note, parsing iso8859-1 french/german/etc as utf8 will generally result in decoding errors which can gracefully revert to 8859-1 safely. If this premise fails too much, we can always change the parser for different charsets - the engine always uses unicode and thus 8859-1 internally.
