In French the quote marks are « and » where in English the character is ", and they sort differently.

The technical term for sort ordering is "collation". As I said, calibre uses the ICU libraries to do sorting. The collation tables for ICU can be found at http://www.collation-charts.org/icu442/. The English collation chart is at http://www.collation-charts.org/icu442/icu442-en.html. I can't guarantee they are correct, but they look right.

@chaley, thanks -- I've linked and made bookmarks for that technical info to consider the next time I'm pulling out my hair in bafflement at technical sort order issues. Great info. I just wouldn't like trying to explain it to a "new" user.
