The UTF-8 support has been steadily improving: For example, icu::Collator::compareUTF8() compares two UTF-8 strings incrementally, without converting all of the two strings to UTF-16 if there is an early base letter difference. http://userguide.icu-project.org/strings/utf-8 For all other encodings you should be able to use an iterator. As to performance I have no idea. The main issue with strxfrm() is its lame API. If it supported returning prefixes you'd be set, but as it is you need >10MB of memory just to transform a 10MB string, even if only the first few characers would be enough to sort...
