Deleting a char inside a textField via code

[Richmond Mathewson]

To make things more complicated:

if one has this:

put numToCodePoint(7418) after the selectedText
put numToCodePoint(7418) after the selectedText
delete the last char of fld "XYZ"

it is the target glyph that is deleted and NOT the useless square

(ie. it is NOT the last char that is deleted).
