On a GNU/Linux system running X.Org, if Emacs is set to use the X11
fixed font 7x13 (e.g. by specifying `--font 7x13' on the command line),
Emacs will use the incorrect font for Unicode (non-ASCII)
characters. Specifically:

- US-ASCII characters are rendered using the correct font.

- Cyrillic (e.g. letters of the Russian alphabet) and some other
  characters (e.g. '¢' (CENT SIGN)) are rendered with the 12x13 font
  instead of the indicated 7x13 font.

- Some characters, e.g. '·' (MIDDLE DOT) and '»' (RIGHT-POINTING DOUBLE
  ANGLE QUOTATION MARK) are rendered with an 8x13 font. This causes
  enabling whitespace-mode to misalign text.

Screenshots can be seen here:

http://emacs.stackexchange.com/questions/20278/unicode-in-x-bitmap-font-uses-a-different-font

I have found that evaluating the Sexpr:

(set-fontset-font "fontset-default" 'unicode "-misc-fixed-*-*-*--13-*-*-*-*-70-iso10646-1")

... causes characters with Unicode codepoints above 256 (incl. Cyrillic
characters) to be rendered with the correct font, but not those in the
codepoint range 128-255. Running set-fontset-font with '(128 . 255) as
the TARGET parameter does not seem to have any effect.

The problem can also be observed in Emacs version 24.5.  Other graphical
applications on the same system using this font do not exhibit this
behavior.
