            Bug ID: 440641
           Summary: Okular Windows filename encoding issue
           Product: okular
           Version: 21.04.3
          Platform: Other
                OS: Other
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: gerald at wireshark.org
  Target Milestone: ---

SUMMARY


STEPS TO REPRODUCE
1. Log into a Windows machine with the code page set to 437.
2. Download "Wireshark User’s Guide.epub" from
https://www.wireshark.org/download/docs/.
3. Try to open the file in Okular.

OBSERVED RESULT

Okular displays the error "Could not open file:///C:/path/to/Wireshark User's
Guide.epub. Error while opening the EPub document." 

EXPECTED RESULT

Okular should be able to open a file with U+2019 RIGHT SINGLE QUOTATION MARK in
its name, such as "Wireshark User’s Guide.epub". The file opens just fine if I
replace the curly quote with an apostrophe (').

SOFTWARE/OS VERSIONS
Windows: Server 2019 1809

ADDITIONAL INFORMATION

This might be due to the fact that Qt mangles command line arguments with
extended characters on Windows:

https://github.com/qt/qtbase/blob/6.2/src/corelib/kernel/qcoreapplication.cpp#L172

We worked around this in Wireshark by fetching the wide version of the argument
vector and converting it to UTF-8 on Windows:
