           Summary: Regression: wqy-bitmap-fonts preferred font over
                    truetype fonts

    Target Release: ---


Failure Case 1: gramps PDF generation
=====================================
gramps is a genealogy application that generates PDF charts.  It seems to ask
pango to choose fonts for it based upon given glyphs.

* In Fedora 10, it successfully output charts using entirely truetype fonts.
* In Fedora 11 however, the UTF-8 Chinese characters are rendered in PDF as
bitmap fonts, which do not scale properly and are ugly compared to the truetype
equivalents.

http://bugzilla.gnome.org/show_bug.cgi?id=576890
Behdad proposes this bug upstream, which would workaround this type of issue at
least for vector rendering cases like PDF generation.  I am uncertain if this
is correct though, and it creates possibly inconsistent behavior?

Failure Case 2: pango-view
==========================
Here is a similar way to reproduce this bug:
LANG=en_US.utf8 pango-view --text "日本語 test" --font "100"
LANG=zh_CN.utf8 pango-view --text "日本語 test" --font "100"

English pango renders the Chinese characters as ugly bitmap.
Chinese pango renders the Chinese characters as truetype.

Workaround: uninstall wqy-bitmap-fonts
======================================
Both of the above problems go away if you uninstall wqy-bitmap-fonts.  But this
should not be necessary.
