Again, not for Achim's benefit, but for anybody else trying to help the other problem
is the complex shaping behaviour involved. This is supposed to be solved in Unicode
using the Mongolian Variant Selector characters, but as far as I know, they're still
undocumented. [I take that back, see:
http://www.unicode.org/Public/3.2-Update/StandardizedVariants-3.2.0.html]. From
somewhere at http://www.ctan.org/tex-archive/language/mongolian/montex/doc/ :
| Mongolian Script, or /bicig/, is a writing with an intriguing
| and complex relationship between the canonical letters of

| canonical letter can assume several shapes. As a rule of thumb,

| word. Only a few letters stay the same, and in rare cases
| there are up to ten possibilities for representing a single
| letter.

| On the other hand, some letters share the same shape in

| letters.
