Not sure about these letters - can someone check please:
Some (?) of them need to be combined with half2 further below.
S -> seen-ar.init.half1
ugrave -> seen-ar.medi.half1
T -> sheen-ar.init.half1
ucircumflex -> sheen-ar.medi.half1
U -> sad-ar.init.half1
udieresis -> sad-ar.medi.half1
macron -> dad-ar
V -> dad-ar.init.half1
dagger -> dad-ar.medi.half1
tilde -> dad-ar.fina
! tilde is not always dad, sometimes it is a complete phrase.

These are supposed to be combined with the seen/sheen/sad/dad above:
cent -> seen-ar.fina.half2
degree -> seen-ar.medi.half2
odieresis -> seen_reh-ar.fina.half2
uacute -> seen_zain-ar.fina.half2



In some AXt fonts, this seems to be a long tatweel.
Sometimes it is the same as tatweel:
grave -> tatweel-ar.alt



These must come last, and in this very order, otherwise they collide with a previous rename:
asciicircum -> comma
z -> guillemetleft
braceleft -> guillemetright

asterisk -> multiply
at -> asterisk

underscore -> divide
asciitilde -> underscore

bracketleft -> bracketright
bracketright -> bracketleft



These seem to stay the same, not sure if true for all AXt fonts:
Delta -> Delta
backslash -> backslash
colon -> colon
exclam -> exclam
period -> period
quotesingle -> quotesingle
slash -> slash
parenleft -> parenleft
parenright -> parenright
hyphen -> hyphen
dollar -> dollar
equal -> equal
percent -> percent
plus -> plus
