Subject: bug#20798: 25.0.50; Some recent change in Emacs trunk spoiled font rendering
Date: Sat, 13 Jun 2015 00:46:32 +0600

***

I've recently re-built Emacs 25 (as I do regularly) to discover that
Greek characters are not rendered with font that I'm using. The font is
‘DejaVu Sans Mono’, and it has all the necessary characters for Greek
script.

I'm setting the font with code that amounts to something like:

  (set-face-attribute 'default nil :family "DejaVu Sans Mono")
  (set-face-attribute 'variable-pitch nil :family "DejaVu Sans Mono")

…and it worked fine until now. Presently, Greek characters are rendered
using this font:

-misc-fixed-medium-r-normal--14-130-75-75-c-140-jisx0208.1983-0

other Unicode characters are rendered with my font of choice.

I've taken a quick look at descriptions of the recent commits and
indeed, some work related to selection of fonts has been done. It would
be good if this regression could be fixed.

I'm absolutely sure that this is due to changes in Emacs trunk because
didn't upgrade/change anything else and it worked fine several minutes
ago on this machine.
