'textAtCursor' does not appear in any 3.9 tkinter/*.py file

'sresults.has_key(textAtCursor)' will see if the hash value of 
textAtCursor matches the hash value of any key and then compare the 
strings.  'failed to convert' suggests to me that you are running 2.x 
and that one of the strings is bytes and the other unicode.
