[pve-devel] [RFC PATCH pve-storage 1/1] fix #3256: Storage: PBS: ensure passwords are saved and loaded as UTF-8

["Laurențiu Leahu-Vlăducu" <l.leahu-vladucu@proxmox.com>]

Previously, no decoding happened, meaning that Perl interpreted the
string as single bytes instead of Unicode code points when reading
the password.

Also, passwords are now explicitly encoded as UTF-8, preventing issues
the other way around.

For more information, please read:
