List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:230177 Archived-At: I am working on feature requests #17684 (crosshairs) and #22873 (multiple= fake cursors). When using move_it_in_display_line_to, =D6=B4=D7=A8=D6=B9 is treated as o= ne 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.wh= at 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 differe= nt characters and each of their individual pixel widths? Thanks, Keith
