[pve-devel] [PATCH cluster] cfs_write_file: fix accidental UTF-8 re-encoding

[Fiona Ebner]

by correclty passing the $force_utf8 flag to
PVE::Tools::file_set_contents(). The idea was that only callers that
are ready will opt-in to the behavior.

When reading files with PVE::Tools::file_get_contents() or
ipcc_get_config(), the UTF-8 flag on the Perl string is not set, even
if the data is UTF-8. Such data would then be encoded a second time,
as reported in the community forum [0] and bug tracker [1].
