Thanks.  I also tried myself with Ubuntu 12.04 by installing Arial
using the ttf-mscorefonts-installer package.  It seems to install a
different version of the Arial font (2.82) than what's bundled with OS
X 10.8 (5.01.2x).  The result is also different from what I showed
before on OS X, but still doesn't look right unlike yours (see the
attached screenshot).

I used libotf 0.9.12, m17n-db 1.6.3, and m17n-lib 1.6.3 on both
platforms.
