The function for composing Thai is thai-composition-function
in thai-util.el and which surely doesn't handle
dotted-circle. I think what we need is a general function
to compose dotted-circle with the following character
artifically. When you eval the following code:
(defun compose-dotted-circle (gstring)
(let* ((dotted-circle-glyph (lgstring-glyph gstring 0))
(following-glyph (lgstring-glyph gstring 1))
(from (lglyph-from dotted-circle-glyph))
(to (lglyph-to following-glyph)))
(lglyph-set-from-to dotted-circle-glyph from to)
(lglyph-set-from-to following-glyph from to)
gstring))
(aset composition-function-table ?◌ '(["◌[^◌ ]" 0 compose-dotted-circle]))
and Thai characters and dotted circle use the same Norasi
font, I think you get a good result. Could you please try?
But, the above function is not yet perfect. In some fonts,
a glyhp of dotted-circle may have positive width, a glyph of
a character following dotted-circle may be narrower than the
glyph of dotted-circle. The function should handle those
cases gracefully. I'm now working on it.
