  Hmm. what I tried very hard to get through to you is that you'd be
better off NOT spending your precious time tweaking with 15-year old
X11 core fonts. It's high time to move on to more advanced font technologies
I mentioned in my previous email.  Please, read materials at URLs
I gave in my messages (one at gtk-i18n and the other at XFree86 font list).

  Qt already does very well with opentype fonts (try Kedit
or other Qt applications and see how well it supports Indic and other
complex scripts) and it even supports mulitple diacritic marks stacked
over a single base character(Latin/Greek/Cyrillic) that is not yet
supported by Pango.
