I understand I should have provided more information about my system.  It's the
current Fedora Development with freetype 2.2.1.  I don't know how to control
whether the interpreter is enabled.

I can see it in the *.sfd files, so it's quite puzzling.  I guess the autohinter
is working differently on different scripts.

There are two hinting related controls in kcontrol.  One is "use sub-pixel
hinting" and the other is "hinting style".  I had the first of them set to RGB
and the second to "full".

Strangely enough, setting "hinting style" to "none" doesn't disable "use
sub-pixel hinting".  I guess "hinting style" is related to autohinting and "use
sub-pixel hinting" is not.

Unfortunately, setting "hinting style" to "none" makes the unwanted color
variations of the text too pronounced, and turning off "sub-pixel hinting" makes
the text blurry.  Turning off anti-aliasing makes the text extremely ugly.  And
that affects Latin symbols too.

I settled for the with blurry text for now (no sub-pixel hinting, style none),
but I guess I'm not actually using the hinting from the fonts, or the
non-antialiased text would be looking better.
