Bug ID: 1634245 Summary: fontconfig-2.12.91 caused wqy-zeihei-fonts lost it's Chinese font name in `fc-list` output Product: Fedora Version: 29 Component: fontconfig Assignee: tagoh@redhat.com Reporter: lovetide@qq.com QA Contact: extras-qa@fedoraproject.org CC: ajax@redhat.com, alexl@redhat.com, fonts-bugs@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, john.j5live@gmail.com, mclasen@redhat.com, pnemade@redhat.com, rhughes@redhat.com, rstrode@redhat.com, sandmann@redhat.com, tagoh@redhat.com

Description of problem: After I upgraded to Fedora 28 from Fedora 27, I found the font displayed in my MATE desktop is not what I configured before, so I try to reconfigured, but I can't found the font name "文泉驿点阵正黑" anymore, (this made Chinese characters in images generated by gnuplot ("文泉驿点阵正黑" font named specifed) unreadable), but I do found it's alternative font name "WenQuanYi Zei Hei Sharp".

Also, I tried the recent released Fedora 29 Beta live CD, same issue still exists.

Version-Release number of selected component (if applicable): 1.12.91-1.fc28 +

How reproducible: Always

Steps to Reproduce: 1. Boot from Fedora 28 or Fedora 29 Beta Live CD, and config the network to make sure it can access internet. 2. Install wqy-zenhei-fonts (issue `su` then `dnf install wqy-zenhei-fonts` in terminal) 3. Issue `LANG=zh_CN.UTF-8 fc-list | grep -i wqy-zenhei.ttc`

Actual results: # fc-list | grep -i wqy-zenhei.ttc /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: WenQuanYi Zen Hei:style=Regular /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: WenQuanYi Zen Hei Sharp,文泉驛點陣正黑:style=Regular /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: WenQuanYi Zen Hei Mono:style=Regular

Expected results: (this is from Fedora 27, with fontconfig 2.12.6-4.fc27) # fc-list | grep -i wqy-zenhei.ttc /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: 文泉驿点阵正黑,文泉驛點陣正黑,WenQuanYi Zen Hei Sharp:style=Regular /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: 文泉驿等宽正黑,文泉驛等寬正黑,WenQuanYi Zen Hei Mono:style=Regular /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc: 文泉驿正黑,文泉驛正黑,WenQuanYi Zen Hei:style=Regular

Additional info: * Fedora 27 does not have this issue. Lastest fontconfig version in Fedora 27 is 2.12.6-4.fc27 * Fedora 29 Live CD still have this issue * Interesting thing, adobe-source-han-sans-cn font is not affected:

# fc-list | grep -i 思源黑体 ... /usr/share/fonts/adobe-source-han-sans-cn/SourceHanSansCN-Normal.otf: 思源黑体 CN,Source Han Sans CN Normal,Source Han Sans CN:style=Normal,Regular ...
