Subject: 24.3; Odd vertical height of some glyphs in certain fonts

From: Reuben Thomas <[email-masked]>

If I set variable-pitch-face to Droid Serif, the right arrow → is much
taller than most other glyphs, effectively forcing extra space after
lines containing it. In DejaVu Serif, this does not happen.

This effect is visible with several other fonts as well: with Calibri,
it does not happen, whereas with Cambria it does, as well as with
Verdana, Ubuntu and Georgia.

In LibreOffice and GEdit this problem does not occur.
