The authors of the library in question? Java? Anybody whose primary
alphabet isn't LATIN1 based? :-)

Only ASCII values store more space efficiently in UTF-8. All values
over 127 store more space efficiently using UTF-16. UTF-16 is easier
to process. UTF-8 requires too many bit checks with single character
offsets. I'm not an expert - I had this question before a year or two
ago, and read up on the ideas of experts.
