When trying to use a modified version of the Lisp snippet from the GNU Emacs FAQ (http://www.gnu.org/software/emacs/windows/Fonts-and-text-translation.html section 5.4) to load BDF fonts:
(setq bdf-directory-list '("~/fonts"))
(setq w32-bdf-filename-alist (w32-find-bdf-fonts bdf-directory-list))
I get a (void-function w32-find-bdf-fonts) error. I've tried this with Emacs for Windows Modified version 23.3-modified-3 (http://vgoulet.act.ulaval.ca/en/emacs/windows) and with EmacsPortable (http://vgoulet.act.ulaval.ca/en/emacs/windows). I'm unable to find any function with that or similar names in the documentation and grepping the Emacs CVS tree for w32-find-bdf-fonts found only the FAQ entry, so I'm guessing it's the FAQ that's wrong. What is the correct code?
It appears that BDF fonts are no longer supported in Emacs 23 on Windows. Refer to etc/NEWS file (which you can access from emacs using C-h n):
** BDF fonts no longer supported on MS-Windows. The font backend was completely rewritten for this release. The focus on Windows has been getting acceptable performance and full unicode support, including complex script shaping for native Windows fonts. A rewrite of the BDF font support has not happened due to lack of time and developers. If demand still exists for such a backend even with the improved language support for native Windows fonts, future development in this direction will most likely be based on the freetype library, giving access to a wider range of font formats.
