But the example given was "SERIAL". "serial" is an English word, not a Turkish
word. It shouldn't really be subject to Turkish locale effects at all. Perhaps
"keyword" wasn't the right word in my message.

I'm wondering if he really expects all identifiers to be subject to this ascii
downcasing. Like, if he had a GÜNAYDIN column he might be surprised to when
günaydýn (where ý is the lowercase dotless i) says column "günaydýn" doesn't
exist.

Or is the real problem simply that both styles of i really ought to match all
the time, ie, that they should really be considered the same letter for
matches? I wonder if there are other locales where that's an issue.
