I got a chance to try this today and found a few errors, which may or may not be down to me not understanding what FontConfig does or what it needs.  But firstly, a problem that definitely wasn't down to me:- 

The first time I ran fc-match it produced this output:- 

"Cannot load default config file" 

I searched my system and sure enough, the file "fonts.conf" had disappeared.  There's no way that I deleted it so I'm guessing it must have been deleted by FontConfig at some stage. When I first installed the file, I noticed a message to the effect that FC would be updating the file periodically, so I had the foresight to make a safety copy.  After replacing the missing file, I ran fc-match again and this time I saw no output whatsoever.  I then ran fc-match in my debugger and saw lots of debug output like the errors I reported the other day on the FontConfig mailing list - I.e. 

FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/._fonts.conf'
FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/%fonts.conf'
FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/.AppleDouble/fonts.conf'
FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/fonts.conf/..namedfork/rsrc'
FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/fonts.conf/rsrc'

and some more output, relating to cache files:-

FT_Stream_Open: could not open `C:/Documents and Settings/All Users/local/etc/fonts/cache/%4398e5d010349f2d591a9b4ff2020a43-le32d4.cache-3

cache-3/rsrc'

I still don't know whether this is normal behaviour or not.  As to the fonts themselves....

This particular app (the one that's giving me the blocky text) was built for Windows, using Visual C++.  Previously I'd already built the same app for Windows (using Cygwin).  The Cygwin version didn't show the blocky text (it seemed to work okay).  When I came to build with VC++ I copied all my ".conf" files to a new location and (although I saw a message about not editing fonts.conf) I did edit the paths, so that FC would know where to find the cache directory and conf files.  Apart from that, I didn't edit anything else.  Nor did I copy or relocate any actual font files from anywhere.  I assumed that Pango (under both Cygwin and VC) would be using my installed Windows fonts and would intelligently find them.  But maybe that's a bad assumption.  Should I have relocated some actual font files too?

I don't know if this gets us anywhere Behdad but I do appreciate your help.
