You're not kidding !!

Microsoft's SimSun-18030 font (available at
<http://download.microsoft.com/download/whistler/Patch/10/NT5XP/CN/GBEXTSUP.msi>) also 
covers the
Mongolian block, but as with the Mac font, whilst this font provides glyphs for the 
individual code
points of the Mongolian block, there are no glyphs for the many standard variants, and 
there is no
mechanism for ligating the glyphs to form typographically correct 
Mongolian/Todo/Sibe/Manchu text
(ditto for Tibetan). Under a new Chinese law all new software sold in China must 
support the new
GB18030 character standard and operating systems must provide support for the Tibetan, 
Mongolian,
Uighur and Yi scripts. Although totally unusable for typesetting Mongolian, Manchu or 
Tibetan text,
the provision of glyphs with a one-to-one correspondence with Mongolian and Tibetan 
block codepoints
ensures compliance with the new law, and thus allows Microsoft and Apple to continue 
to sell their
operating systems in China.

As far as I am aware there is nobody out there currently engaged in the production of 
a proper
Unicode Mongolian/Manchu font - but I'd pleased if someone could prove me wrong on 
this.

The 1999 report "Traditional Mongolian Script in the ISO/IEC 10646 and Unicode 
Standards" by Myatav
Erdenechimeg, Richard Moore and Yumbayar Namsrai, available in postscript form at
<ftp://ftp.iist.unu.edu/pub/techreports/report170.tar.gz>, is the key document to 
understanding how
to write Mongolian and Manchu in Unicode, and should be read in conjunction with 
Unicode's
"Standardized Variants" page at
<http://www.unicode.org/Public/3.2-Update/StandardizedVariants-3.2.0.html>.
