The one line script was:
perl -e 'open(I, "lang.lng"); while(<I>) {next if /^[\t ]*#/; next unless
/\w/; s/\s*$//; print;}'
The text file lang.lng was:
line1=mâta
lala=tâta
It is not a UTF-8 encoded file, but a simple ANSI/Unix end of line file
that contains some special chars in latin1 character set.
The program works fine with Perl 5.8.3 under Red Hat, but it gives me
that error if running it on another system where I have perl 5.8.0.
However, I guess this has nothing to do with the version of perl....
Actually, it might have everything to do with the version. 5.8.0 would use
the current locale setting on a RedHat OS: if the locale was set to
something referring to utf-8, Perl 5.8.0 would assume a default behavior
that would try to treat every input file as a utf-8 file.
This was soon recognized as a bad idea, and more recent versions will
always open input files as "raw" (no special character semantics), and you
have to specify ":utf8" via the open statement or binmode in order to
interpret the input data as utf-8.
To get your one-liner to behave the same on 5.8.0 as it does on 5.8.1, you
need to add "use bytes;" -- this is not necessary (but does no harm) when
running 5.8.3.
