If you want to delete the last characters by script, why not something like:
delete last char of fld X
This works, of course, if it is the last char in the field.
Or a more complex version might be
put the selectedChunk into tWhere
put word 2 of tWhere into tStart -- staring char position of the cursor
put word 4 of tWhere into tEnd -- ending char position of the cursor
if tStart > tEnd then -- just an insertion point
delete char tEnd of field X -- delete the character just before the
insertion point
else -- some field content is selected, so
delete char tStart to tEnd of fld X -- delete the selected field content
end if
While this sort of thing works it mucks up the font settings of the
field (and I'm using fields with multiple font settings).
I did this from memory, so check the dictionary for the exact
expressions returned by the selectedChunk function.,

Digging further . . .
I found out that the problem appearas:
1. NOT to be with LiveCode.
2. NOT to be with MacOS.
Because using a font other than my one works well.
So?
What hidden aspects of my Devawriter.ttf font are gumming up the works?

How does one do this "programmatically"?
Here's the (admittedly odd scenario):
Unicode behaves inconsistently in various marginal cases with
Devanagari script,
and what happens is that the first time one sends this:
put numToCodePoint(7418) after the selectedText
one ends up with a useless square.
But if one does this:
put numToCodePoint(7418) after the selectedText
put numToCodePoint(7418) after the selectedText
one ends up with the useless square PRECEDED by the target glyph.
So, the 'clever' work around might be to do this:
put numToCodePoint(7418) after the selectedText
put numToCodePoint(7418) after the selectedText
followed by deleting the useless square
However doing this:
put numToCodePoint(65288) after the selectedText
results in another useless square.
