I have a little advise for the text editor designers. I think i am
either the stupidest or the smartest man in the universe if i write it
A caret is a flashing line, block, or other picture in the client area
of a window, it indicates the place (between two characters) at which
text will be inserted (or the edge of the text to be selected or
deleted). What does it mean? Between? There is no "between" in the
bidirectional text, the previous and the next character are not
necessary nearby! There is no distinct place for the insertion because
the place depends of direction of the inserted characters.
Other example, without bidi. You see:
Where is your caret? After é? after  ́ ? between e and  ́ ? Press
←left key. Nothing changes. Now you sure you are between e and  ́ . Or
you keyboard is broken!
Red e with green acute is more informative and comprehensible picture!
It is very clear mnemonic: a red character before the current position
and a green character after them. The direction is always from red to
green. If you can't use colors: render all the text to frame0, the
"red" character to frame1, the "green" character to frame2, on timer
show frame0, frame0 xor frame1, frame0 xor frame2. It is blinking :)
And one more thing. "Red" and "green" characters have to became
visible ever (e.g. if it is a control character, blank (no visible
edges is no good), soft hyphen, virama).
