You could moreover add the following to the field's script.
on rawkeyup k
switch k
case 65288 -- backspace
put word 4 of the selectedChunk into cx
if char cx of me is among the items of \
(numToCodePoint(0x23CE),numToCodePoint(0x21E5),numToCodePoint(0x00B7))
then delete char cx of me
break
case 65535 -- forward delete
put word 2 of the selectedChunk into cx
if char cx of me is among the items of (numToCodePoint(0x200A),cr,tab)
then delete char cx of me
break
default
pass rawkeyup
end switch
end rawkeyUp
There is still more to do, e.g. when typing after a return symbol...
Hope you are (as I did) sharing your working edit code when done.
