The alignment of unicode combining accents seems reasonable in a
fixed-width font, but is clearly off for a variable-width font.
For instance, the following string:
xyz: ç̄̓ö̈ó̀l̗̈
Looks OK with font "DejaVu Sans Mono", but messed up with font "DejaVu
Sans". [As far as I can tell, these fonts have roughly the same
coverage, so I'm guessing that's not a problem.]
With the cursor positioned over the "c", for instance, I can use `C-u
C-x =' to see:
Composed with the following character(s) "̧̄" using this font:
xft:-unknown-DejaVu Sans-normal-normal-normal-*-12-*-*-*-*-0-iso10646-1
by these glyphs:
[0 2 99 70 7 -2 6 8 2 nil]
[0 2 807 728 0 -4 -2 0 2 [-4 0 0]]
[0 2 772 693 0 -5 -1 9 -8 [-4 0 0]]

In my environment, Emacs displays those combining accents
correctly even with "dejavu sans" font (see the attached image).

Ah, that is a problem of m17n-flt. It is fixed in the next
release. You can also try the latest CVS code:
% cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co m17n-lib
