OK, thanks for verifying this works.

FTR, what font are you using for this script?

Thanks.  However, I think I'd like to separate this line from the
existing Mongolian line (which uses the Cyrillic script).  I thought
about labeling it "Mongolian Traditional:, WDYT?  Alternatively, we
could rename the existing line to "Mongolian Cyrillic", if the
traditional Mongolian script is back in wide use nowadays.  In any
case, I will need to know how "Mongolian" is written in the Mongolian
script, can you tell that as well?

Great, thanks.

I already did that, in the commit I installed today.

Thanks.
