I guess I was looking for a generic term for uppercase/lowercase. I picked "case conversion" instead.

I did an 'exchaustive' search for 'exchaustive' across the code base and found  two comments in `LocaleData` and `LocaleData.cldr` in `jdk/test/jdk/sun/text/resources`.

Would you like me to update these as well while we're here, or should we avoid getting out scope for this PR?
