Current code try to compose any non-spacing mark characters
with the previous spacing characters. But, the detection of
non-spacing mark is done by (= (aref char-width-table CH)
0). This should be changed to check char-code-property
`general-category'. I'll fix the code soon, but at the
moment, you can workaround the problem by this:
(aset composition-function-table #x200f nil)
