Kai> Thanks. I’ve got it work.
Kai> Besides the pattern problem, there were two missing pieces:
Kai> (1) canonical-combining-class, and
Iʼm surprised you needed to override that, but composition has many
dark corners.
Kai> (2) `compose-' to actually compose it into one glyph.
`font-shape-gstring' alone does not work.
Kai> This is the result:
Kai> (defun zbalermorna-setup ()
Kai> "Set up the composition rules for zbalermonrna."
Kai> (interactive)
Kai> (dolist (v (number-sequence #xeda0 #xeda9))
Kai> (put-char-code-property v 'canonical-combining-class
(encode-composition-rule '(tc . bc))))
Kai> (let* ((c "\\([\uED80-\uED97]\\|\uEDAA\\|\uEDAB\\)")
Kai> (v "[\uEDA0-\uEDA9]")
Kai> (dot "\uED89")
Kai> (h "\uED8A")
Kai> (pattern1 (concat c v))
Kai> (pattern2 (concat v h v)))
Kai> (set-char-table-range
Kai> composition-function-table '(#xeda0 . #xeda9)
Kai> (list (vector pattern2 2 #'compose-gstring-for-graphic)
Kai> (vector pattern1 1 #'compose-gstring-for-graphic)
Kai> [nil 0 font-shape-gstring]))))
Eli, since these are PUA, can we still add them to Emacs?
Thanks
Robert
