When does toUpperCase(ch) == ch ?

I intend on testing this with a few perl scripts later using the db, but
thought I'd pose the question to see if anyone has a quick answer:

Is it true that if a character's general category is neither Ll nor Lt,
then the uppercase character is simply the character itself?
