A. =D8=B9 =D9=84 =DB=8C - these are the "isolated" types. B. =D8=B9=D9=84=DB=8C - this is a final, medial and initial type. C. =D8=B9=D9=84 =DB=8C=E2=80=8E - the isolated =DB=8C should be joined w= hen the space is removed.=20 This is the bug demonstrated. 0. Start emacs: $ emacs -Q 1. Output =D8=B9=D9=84=DB=8C with a bold face in the appropriate font: (progn (setq buffer-face-mode-face '(:family "DejaVu Sans Mono"=20 :alternate-families "Monaco" :height 100)) (buffer-face-mode) (buffer-face-set 'bold) (newline) (insert " =D8=B9=D9=84=DB=8C")) =D8=B9=D9=84=DB=8C 2. Change to a regular face: (buffer-face-set 'default) =D8=B9=D9=84=DB=8C What happens is =DB=8C (ARABIC LETTER FARSI YEH) switches from the final = to=20 the isolated type. This is incorrect since there should be no difference in the=20 representation when eval-ing the following: (buffer-face-toggle 'bold) The output of describe-char on the emboldened and regular differs on the=20 following: Regular (incorrect): Composed using this font: =20 xft:-unknown-KacstDecorative-normal-normal-normal-*-11-*-*-*-*-0-iso10646= -1 by these glyphs: [0 0 0 107 5 0 6 5 2 nil] Bold (correct): Composed using this font: xft:-unknown-KacstOne-bold-normal-normal-*-11-*-*-*-*-0-iso10646-1 by these glyphs: [2 2 0 200 7 0 8 2 4 nil] Please note that this bug does not exist on 24.3.1, and I apologise if=20 it is a problem with my compilation settings.
