Hi,
1. The characters overlaps each other and can not be set size.
The is a mini example.
\definefont[song][name:simsun at 12pt]
\starttext
\song 测试
\stoptext
The attachment is its output.
2. the cid fonts cause MkIV gives a waring as following:
LuaTeX warning: lua-loaded font [44]
(/usr/share/fonts/adobe/AdobeSongStd-Light) has no characters!

Best regards,

Verified.
This actually looked fine here with the current 2010.05.21 11:10,
but the beta 2010.05.22 12:06 MKIV is broken, producing the same
output you have.

Verified, same here, even with the official current.
\definefont[song][name:adobesongstd-light at 12pt]
\starttext
\song 测试
\stoptext
Best wishes,
Taco

Some debugging applied. This line in font-otf.lua:
tfm.format = (metadata.order2 == 1 and 'truetype') or 'opentype'
produces 'opentype' for simsun.ttf, and so all glyphs are printed
at 2.048 times the normal size in the PDF output.
This is because the key metadata.order2 doesn't exist _anywhere_ in
the context source (except in this test). But neither did it exist in
the official current. The context current did tfm.format later.
Patch to revert back to the current's behaviour:

Something is broken in the handling of the 'subfonts' key, but I haven't
figured out what (yet?).
Best wishes,

The 'merge cid fonts' enhancer is broken. It starts by testing
data.glyphs, but this is the field it is supposed to fill (!).
The patch is a one-liner:
--- font-otf.lua~ 2010-05-23 10:20:10.979586135 +0200

I'm wondering if the 'if' statment is even necessary, metadata.order2
doesn't exist neither in context nor in luatex generated tables, so the
above statment always resolve to 'tfmtable.format = specification.format'.
