Actually sorting should be fine. The order of UTF-8 will always be the same as the codepoints encoded under it if you sort it as binary. I really appreciate this property of UTF-8, and I can highly recommend to do a pen&paper exercise to see why it preserves order :-) It wouldn't work if you want any type of normalisation and especially solving composition/decomposition.
