I just got an SAA5054 (date code 8510) and the character it has at 5/13
is different from the one in the datasheet. The real one lacks the
pixel in the bottom right corner, so it's more like a Ugrave than a
ugrave. However, it would be weird for a character set to include the
capital but not the lower case, and the corresponding character set in
ETS 300 706: May 1997 (the French option in table 36) is obviously
lower-case. So I think it's semantically lower-case, whatever it looks
like.
As for the thing I was intending to check, yes the accent does join onto
the letter.
