I think most software (like programming languages) has actually switched to UTF-8 for internal representation, because it has low footprint (for most applications). You give up efficient O(1) indexing, but I don't think you typically need that. Indexing is far less meaningful for Unicode compared to ASCII.

  trim, contains, split (at whitespace, or at a given byte position) can all be implemented efficiently in UTF-8.
