  Yeah, that's what I thought I had found in the source
when I wrote my original report. Then you wrote that it's fine and
I beleived you thinking that I had yet another instance of memory
failure :-)

  Wow, that will be nice.

  I've just checked it under Linux with my test program and CODE2001
font and it worked fine. The default Cmap selected was 3.10  and
FT_Select_Charmap with FT_ENCODING_UNICODE correctly selected 3.10 as well.

  BTW, I heard that MacOS X has a Japanese font (Hi??) with hundreds of
Plane 2 characters. I guess this font has two UCS-4 Cmaps (Apple's and
MS') and your concern is justified :-)  I was also told that Chinese
version of MS Office XP includes Simsun (founder extended?) font with
thousands of characters in Plane 2.

  You're welcome and thank you.
