Subject: IT testing for multiple characters (ִרֹ) that occupy 1 display string.
Date: Sun, 30 Sep 2018 17:14:04 -0700	[thread overview]
Message-ID: <m2in2mplpv.wl%esq@lawlist.com> (raw)

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
