ps-print: Patch for international printing with bdf fonts

The attached patch tries to enable printing using bdf-fonts. With this patch I can print most languages from the hello-file. Can you please check whether this patch makes sense and if yes include it into the XEmacs packages? According to the comment on top of /usr/share/xemacs/xemacs-packages/lisp/ps-print/ps-mule.el one can set (setq ps-multibyte-buffer 'bdf-font) and then bdf fonts will be embedded into the PostScript output. This is rather ugly, but makes it possible to print (almost) all languages shown on the hello page (M-x view-hello-file). With GNU Emacs this works, but when I tried it with XEmacs it failed. One reason is that ps-mule.el uses a few coding-systems which have different names in XEmacs, I could solve that by defining aliases like: +(define-coding-system-alias 'greek-iso-8bit 'iso-8859-7) +(define-coding-system-alias 'hebrew-iso-8bit 'iso-8859-8) +(define-coding-system-alias 'cyrillic-iso-8bit 'iso-8859-5) +(define-coding-system-alias 'vietnamese-viscii 'viscii) +(define-coding-system-alias 'chinese-big5 'big5) +(define-coding-system-alias 'thai-tis620 'tis-620) Is this a correct solution? Another problem is that 'coding-system-p' works differently on XEmacs, which I could fix with: - (cond ((coding-system-p encoding) + (cond ((if (string-match "XEmacs" emacs-version) + (find-coding-system encoding) + (coding-system-p encoding)) The third problem I found was that the variable 'enable-multibyte-characters' happened to be nil in ps-mule.el, which also caused problems with multibyte printing. The doc string of this variable says: `enable-multibyte-characters' is a built-in boolean variable. Value: t Setting it would make its value buffer-local. Documentation: Emacs Compatible; Unimplemented Non-nil means the buffer contents are regarded as multi-byte form of characters, not a binary code. This affects the display, file I/O, and behaviors of various editing commands. Setting this to nil does not do anything. If setting this to nil doesn't do anything, then I can just as well assume that this is always t in ps-mule for XEmacs: (and (boundp 'enable-multibyte-characters) - enable-multibyte-characters + (if (string-match "XEmacs" emacs-version) + t + enable-multibyte-characters) Apart from the hunks explained above the patch does some other trivial things like changing the directory where the bdf fonts are: - '("/usr/local/share/emacs/fonts/bdf")) + '("/usr/share/fonts/bdf")) (that's where they are on SuSE Linux) and using gulim24.bdf instead of hanglm24.bdf (korean-ksc5601 - (normal bdf "hanglm24.bdf" ps-mule-encode-7bit 2)) + (normal bdf "gulim24.bdf" ps-mule-encode-7bit 2)) because Korean users liked gulim24.bdf much better than hanglm24.bdf. Using the attached patch and (setq ps-multibyte-buffer 'bdf-font) I was able to print all languages from the hello-file except Amharic, Thai, and Tigrigna. When testing the bdf printing with the hello-file you have to remove the lines with these languages, otherwise you will get an error. I have no idea how to make it work for these languages as well. For testing the bdf printing you need the GNU intlfonts-1.2. The following tarball contains them in bdf format and also includes gulim24.bdf: http://www.suse.de/~mfabian/misc/bdf-fonts.tar.bz2 -- Mike Fabian <mfabian(a)suse.de&gt; http://www.suse.de/~mfabian 睡眠不足はいい仕事の敵だ。
