Interestingly, when I run this font and the test file through m17n-edit
(after some debugging why the font was not recognized :-(), it seems
fine there.  So in this case it does not seem to be a problem with m17n,
but actually with Emacs.

With m17n-edit, the text is run through COMBINING.flt (according to
MDEBUG_FLT=3), with Emacs, no FLT is triggered at all.  Which makes me
suspect that Emacs does not use m17n for this font at all (?).
