IT testing for multiple characters (ִרֹ) that occupy 1 display string. |

I am working on feature requests #17684 (crosshairs) and #22873 (multiple fake
cursors).
When using move_it_in_display_line_to, ִרֹ is treated as one display string;
however, it is 3 different characters occupying 3 HPOS. it->c only reports
1460.
I initially guessed that this was a composition situation, however, it.what
returns a 0, which is the same as any other regular character.
Q: How do we test for this situation, so that we know all of the different
characters and each of their individual pixel widths?
Thanks,
Keith
