Thanks. This really confirms your claims.

I can not reproduce it, nevertheless the following change may have
some effect on your system:

I'm not sure I understand which encoding/decoding you have in mind.
The $unicode_aware is there because certain arguments (e.g. to binmode)
are syntax errors for pre-5.8 versions of Perl, so using such options
need to be restricted to Perl that understands them. The purpose
of logging LANG etc. at startup is to help troubleshoot the kind
of problems you have now, but were only common with a change from
Perl 5.6.x to 5.8.0. It's been a long time since I heard of
similar problems, versions of amavisd-new that were developed
when Perl was at 5.8.0 and 5.8.1 tried to works around all such
problems known at that time. But it is possible there are still
some corner cases hidden.
