I'll bet this line is coming from a hyphenation patterns file. _all_ file I/O has to be utf-8 encoded, including patterns. Unf., lots of patterns files are using EC font encoding as a file encoding, and are therefore not valid utf-8. I do not normally use LaTeX any more, making it hard for me to give exact advice, but you either need to find a set of patterns for this language that _is_ utf-8 encoded (ConTeXt ships with such pattern files, and I understood that there is a set of similar files that come with XeTeX), or you have to disable the language(s) that is causing you grief by means of some babel configuration file.
