Files silently skipped when extracting from 7z archive

[stephane352]

Hello,
Extract is working fine with zip files.
Unfortunately, when working with 7z files, if the archive contains file names with accents like Café.txt or Stéphane.txt, the file is not extracted (and sometimes other files in the archive as well).
This is a serious issue because the user is not notified that some files were skipped and only the administrator can see an error in the Nextcloud server logs (e.g. "Warning core normalizing failed for "Café.txt"").
This happens in Nextcloud 24.0.9 as well as in 26.0.4, with the latest version of Extract.
Would it be possible to fix this please ?
Thanks in advance.
Kind regards,
Stéphane
