From Options > Settings, Advanced tab you can set 7z / p7zip syntax level, in order to exclude switches which are more recent than a specified version. in 9.9.0 release it is possible to fall back to syntax compatible with 23.01 and 21.07 releases, the latter very similar to syntax of 17.x line. I hope to expand the compatibility list in future.

Thank you for testing the issue further. I found no reliable solution which consistently work on my Windows test machines, testing various locales and various input filename encoding. Conversely the issue does not apply to non-Windows test machine (BSD, Linux, macOS) which consistently enforces UTF8 use through all system components.

Thank you for reporting the issue. Backend for some formats (Brotli, Quad, Zstd) seems running in this issue on Windows. Backend for other formats (7z, zip, tar, arc, pea, zpaq) dopes not experience this issue. I'll test the issue further for a possible workaround.

The deletion actions in the dropdown menu of deletion toolbar button were added a while ago in order to operate on entire files rather than of items inside archives. Confirmation messages in Quick delete, Zero delete, and Secure delete makes it a bit more clear, but the dialog lacks for the Move to recycle bin element, making the behavior unexpected. Probably the best option would be, while browsing archives, to either clearly label that group of actions (e.g. Delete entire archive) or alternatively...

There is currently a reduced set of switches that can be passed to the Windows installer, you can find information on https://peazip.github.io/peazip-command-line.html in the section "PeaZip Windows installer syntax examples". If a more fine grained configuration is needed it could be done with other means, i.e. copying a customized conf.txt configuration file after the installation.
