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

Summary: Regression: wqy-bitmap-fonts preferred font over truetype fonts Product: Fedora Version: rawhide Platform: All OS/Version: Linux Status: NEW Keywords: i18n Severity: medium Priority: low Component: wqy-bitmap-fonts AssignedTo: fangqq@gmail.com ReportedBy: wtogami@redhat.com QAContact: extras-qa@fedoraproject.org CC: petersen@redhat.com, fangqq@gmail.com, fedora-fonts-bugs-list@redhat.com, fedora-i18n-bugs@redhat.com Classification: Fedora 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.
