Fonts for texttopdf

[Tobias Hoffmann]

Hi,
I'm currently working as GSoC Student[1] on the texttopdf[2] and 
pdftojis[3] filters for a PDF based workflow on *nix.

The texttopdf filter (which is derived from texttops of CUPS) should now
support non-latin scripts, e.g. CJK and right-to-left. texttops already 
some support, but one problem is, that the currently used font (Courier)
is not enough.

So my question are:
- Which is a good font (on which platform) for embedding
   for the purpose of pdf printing workflow, and
- What is the best way of going about it (code to scavenge/reference),
   as for example CJK fonts might be quite large, and OTF is not 
(easily) supported for PDF<1.6, to name a few constraints.

   Tobias
