Re: char-displayable-p issue

[Michael Mauger]

I can't reproduce that bug. When I turned on ruler-mode, I see both characters in the ruler head. Isn't it a bug specific to Windows?

Yes, it seems the problem is specific to Windows. Work well on my GNU/Linux box.

I'm not sure that this is just a Windows issue -- it may affect some X implementations as well.  The problem seems to be that the wildcard pattern generated in `char-displayable-p' is not matching multiple hyphen separated portions of the font name.  That is, '-*-*-iso8859-1' doesn't match any fonts while '-*-*-*-*-*-*-*-*-*-*-*-*-iso8859-1' does.

Here's a patch that corrects the problem (and should work reliably on all X implementations) but which runs very slowly on Windows. 

Please review...
