ucs-normalize and diacritics

[Robert Pluim]

Hi,

in
<https://emacs.stackexchange.com/questions/43757/combining-diacritics-not-combining-visually>
someone noted that â (that is LATIN SMALL LETTER A followed by
COMBINING CIRCUMFLEX ACCENT) was not visually shown as â (LATIN SMALL
LETTER A WITH CIRCUMFLEX). I can play around with the various
ucs-normalize-* functions and get that to happen, but Iʼm just curious
why it doesnʼt happen automatically (assuming it should, of course. I
couldn't find any documentation on this kind of stuff).

Thanks

Robert
