            Bug ID: 107370
           Summary: fc-query doesn't find non-english family names in some
                    fonts
           Product: fontconfig
           Version: 2.12
          Hardware: Other
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: fc-query
          Assignee: fontconfig-bugs at lists.freedesktop.org
          Reporter: cwryu at debian.org

fc-query couldn't find Korean family of some Korean fonts in my laptop. I
believe this is the same with other languages.

Korean fonts usually have multiple "family" string, like "Baekmuk Batang" in
English and "백묵 바탕" in Korean. But fc-query couldn't find the Korean version in
some Korean fonts. In other Korean fonts, fc-query has no problem to find all
the family strings.


$ ./fc-query/fc-query -b /usr/share/fonts/truetype/baekmuk/batang.ttf |grep
family
        family: "Baekmuk Batang"(s)
        familylang: "en"(s)
$ ./fc-query/fc-query -b /usr/share/fonts/truetype/nanum/NanumGothic.ttf |grep
family
        family: "나눔고딕"(s) "NanumGothic"(s)
        familylang: "ko"(s) "en"(s)
$

Old 2.12.4 version worked OK.

$ ./fc-query/fc-query -b /usr/share/fonts/truetype/baekmuk/batang.ttf |grep
family
        family: "Baekmuk Batang"(s) "백묵 바탕"(s)
        familylang: "en"(s) "ko"(s)
$
