One issue you might not realize is that the sort order for some locales
ignore symbols and spaces for initial scans, so for example, you might
find that "A Z" > "AB" while " " < "B". Specifically, for the data you
gave, en_US would order them "tan, fang", "tang, s. c.", "tan, weihong"
while C would order them "tan, fang", "tan, weihong", "tang, s. c.".
