             Bug #: 48046
           Summary: ttc<->ttf fallback is expected for CJK font list in
                    GlobalParamsWin.cc
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Windows (All)
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: general
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: mpsuzuki at hiroshima-u.ac.jp


Since git dae29c6c201cd69cbf4f008de865cc19a36f29b3, there is a fallback
for missing CID-keyed fonts for CJK scripts. However, at present,
the fontlist in GlobalParamsWin.cc is designed to have fully specified
basename of the font file. Thus, if a platform has "msmincho.ttc" but
not "msmincho.ttf", the mechanism cannot find MS-Mincho to fallback.
The versions of Microsoft Windows sold in Japanese market have mainly
msmincho.ttc. To support both platforms having "have-msmincho.ttc-but-
no-msmincho.ttf" and "have-msmincho.ttf-but-no-msmincho.ttc", some
fallback (or listing multiple font files as "one of following candidates"
for a fallback item) is expected. I will try to improve.
