Created attachment 1279712 [details] Alternate font file clR9x15.pcf displayed correctly Alternate font file clR9x15.pcf displayed correctly Alternate version of clR9x15.pcf retrieved from https://github.com/rdebath/SLS-1.02/blob/master/usr/X386/lib/X11/fonts/misc/clR9x15.pcf displayed correctly. For the Fedora font file clR9x15.pcf, command 'file clR9x15.pcf' returns "X11 Portable Compiled Font data". For the alternate font file clR9x15.pcf command 'file clR9x15.pcf' returns "X11 Portable Compiled Font data, LSB first". According to https://bugzilla.gnome.org/show_bug.cgi?id=768886#c3, this problem is not related to gnome-font-viewer but rather to freetype. Moreover, font file clR9x15.pcf can be used without issue in X applications like xterm or xfontsel. Issue also affects Fedora 26 including package freetype-2.7.1-6.fc26. The problem with the font is that the encoding there is not unicode encoding and hence its charmap stays undefined in FTFace. Freetype recognizes just ISO10646 and ISO8859-1 here. I'll look whether this is correct tomorrow. Font properties returned by xlsfonts: DIR MIN MAX EXIST DFLT PROP ASC DESC NAME --> 0 127 all 0 21 12 3 -schumacher-clean-medium-r-normal--15-150-75-75-c-90-iso646.1991-irv Since the ISO646.1991-IRV charmap is ASCII, I've asked freetype's upstream to add it to the set of recognized Unicode charmaps. Werner added it today in this commit: http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=082f2faf5007812bac6a1f783c7dcc6f49d761fe. The other fonts with other charmaps needs to be handled on the glyph base in the application since freetype recognizes Unicode charmaps (FT_ENCODING_UNICODE) and others (FT_ENCODING_NONE) only in the PCF (and BDF) driver. freetype-2.6.5-9.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2017-f35e321a3b freetype-2.7.1-8.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-9956dd8d80 freetype-2.7.1-8.fc26 has been pushed to the Fedora 26 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2017-9956dd8d80 freetype-2.6.5-9.fc25 has been pushed to the Fedora 25 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2017-f35e321a3b Further inspection has revealed that a fair number of X fonts has the same problem, for instance the DEC terminal font which is of encoding type "dec". Launching 'xfontsel' and browsing through the encoding list exhibits a number of encodings which are not yet considered either. However, there are even non-X fonts like /usr/share/fonts/sil-padauk/Padauk-Bold.ttf which are not displayed by gnome-font-viewer (the regular font variant displays just fine). freetype-2.6.5-9.fc25 has been pushed to the Fedora 25 stable repository. If problems still persist, please make note of it in this bug report. freetype-2.7.1-8.fc26 has been pushed to the Fedora 26 stable repository. If problems still persist, please make note of it in this bug report. |
Created attachment 1279709 [details] Sample font file clR9x15.pcf Description of problem: Using gnome-font-viewer-3.22.0-1.fc25 of current Fedora 25, various fonts are merely shown as a white window, e.g. clR9x15.pcf. Version-Release number of selected component (if applicable): gnome-font-viewer-3.22.0-1.fc25 How reproducible: Always Steps to Reproduce: 1. Install package xorg-x11-fonts-misc. 2. Open font file clR9x15.pcf in gnome-font-viewer. Actual results: gnome-font-viewer displays a white window. Expected results: gnome-font-viewer displays the chosen font set. Additional info: - After opening /usr/share/X11/fonts/misc in "Files", a fair number of fonts are merely represented by empty thumbnails. - Issue also applies to TTF font file symbol.ttf.
