Martin was assuming you would write your own function "lookupchar" to do
the actual work, but since you are new at this, the function is actually
exactly what you are asking about.

To reference a field, you'd need to add the object descriptor. That is,
change "me" to "field 'edtText'". But "me" is okay, leave it that way as
long as the script is in the field itself.

Look up the "selectedChunk" term in the dictionary. This gives you the
position of the insertion point, or the position of any selected text,
in the format:
char x to y of field "whatever"
If x is smaller than y, a range of characters is selected. If x is
larger than y, the insertion point is blinking between two characters.
Your script should check to see whether x is smaller than y. If so,
you've got a selection that spans characters, and x-1 would be the
previous character, and y+1 would be the next one. If x is larger than
y, the insertion point is between characters and x+1 would be the next
character and y-1 would be the previous one.
Once you have determined whether you have a range of text or not, you
can put extra text either in front of or after the selected chunk:
put "abc" before char x of field "whatever" -- works for a range
put "abc" after char y of field "whatever" -- works for a range
put "abc" before char y of field "whatever" -- for non-range
put "abc" after char x of field "whatever" -- for non-range
