Sample Files

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

Start by reproducing the g-l subtitle-selection flow on Windows Git Bash with the attached sample.zip and the subtitle path shown in output.txt. Trace the failure reported as “Illegal byte sequence” while extracting subtitles, then verify that g-l displays the subtitle list for paths containing spaces and the shown non-ASCII characters.
