in thread How do I use the "File::ReadBackwards" and open in "Unicode text, UTF-32, little-endian" mode

I have found a simple solution for my particular case, as I know that I only want to match certain strings from the log file and none of the match strings will be none ASCII characters.

I can use the ReadBackwards to read the line in then strip out none ASCII and null characters.

my $ERRORLINES_IN = File::ReadBackwards->new($logfile) or die "$logfil +e : $!\n"; while (defined($logline = $ERRORLINES_IN->readline)) { $logline =~ s/[^[:ascii:]]//g; $logline =~ s/\0//g;

It's not a perfect solution but it works for my case.
