Well, better filing separately for what you complain on screenshot1 and 2.

However we have inconsistent bug in Pango (this, particularly for screenshot1)
and Qt (Bug#222781). I thought we had discussed that before though, let me
explain that again.

Since the backspace key works for deleting a character but not the combined one,
it's pretty likely to recombine between the characters around the deleted one.
once it happens, current position isn't valid position to be stopped the cursor
anymore. but it's hard to determine which one is preferable to be moved, and
people usually may wants to correct something after deleting the backspace key.
the recombination should be a side-effect in the most cases IMHO.
So the cursor doesn't have to be moved anywhere and just keeps current position,
but needs to notify current state to the users.

IMHO there are two possible solutions for this:
1. improve UI that let people know the current cursor possition is somewhere in
the combined character, instead of blinking two cursor between a combined character.
2. give up to manage the backspace key as deleting a character, and have the
same behavior to the delete key. i.e. delete the combined character.

Which one do you prefer? or another opinion are welcome.


BTW for screenshot 2, there seems to be a character that is_cursor_position is
true unexpectedly.
