Extracting the 4 unique family names I could find, annotating with 
interpretation
of the constants:

No. 1
  platformID: 1        [Macintosh]
  languageID: 0 (0x0)  [English]
  encodingID: 0        [Roman]
      nameID: 1

      string: %82 'c' %82 'e' %82 'f' %95 %bd %90 %ac %96 %be %92 %a9 %91 %cc 
'W' '7' 

This one looks misencoded. This is Japanese/Shift_JIS, but tagged as 
"English/Roman"

No. 9
  platformID: 1        [Macintosh]
  languageID: 11 (0xb) [Japanese]
  encodingID: 1        [Japanese]
      nameID: 1
      string: %82 'c' %82 'e' %82 'f' %95 %bd %90 %ac %96 %be %92 %a9 %91 %cc 
'W' '7' 

This is Japanese/Shift_JIS, correctly tagged.

No. 16
  platformID: 3             [Windows]
  languageID: 1033 (0x409)  [English United States]
  encodingID: 1             [Unicode]
      nameID: 1
      string: %00 'D' %00 'F' %00 'G' %00 'H' %00 'S' %00 'M' %00 'i' %00 'n' 
%00 'c' %00 'h' %00 'o' %00 '-' %00 'W' %00 '7' 

The English name, correctly tagged.

No. 24
  platformID: 3             [Windows]
  languageID: 1041 (0x411)  [Japanese Japan]
  encodingID: 1             [Unicode]
      nameID: 1
      string: %ff '$' %ff '&' %ff ''' '^' 's' 'b' %10 'f' %0e 'g' %1d 'O' 'S' 
%00 'W' %00 '7' 

The Japanese name, encoded as Unicode.

Looking at this, I have no idea why the code in FreeType CVS isn't working; the 
check 

 ( rec->languageID & 0x3FF ) == 0x009 

Should have caught No. 16, and it should have used that name, not No. 24.

Maybe David has some idea.

Thanks,
