Sorry, "extended" ascii (code page 437), been using it since 1984 and old 
naming habits die hard.

Yes, 8-bit ASCII, here is a translation table.

ASCII|UTF-8
  00 | 00
  01 | 01
...
  7E | 7e
  7F | 7f
  80 | c2 80
  81 | c2 81
...
  BE | c2 be
  BF | c2 bf
  C0 | c3 80
  C1 | c3 81
...
  FE | c3 be
  FF | c3 bf

No, only when not ENCODED properly.

UTF-8 is very, very, likely going to stay.

That is the point. The OP complaines about ASCII being sent when labeld as 
UTF8, as such it created invalid UTF8 sequences.

Not exactly a valid test, besides it works for me. The issue is internal ascii 
data being written as ascii but instructing consumers
it is uft8. 

$ cat utf8_test.pl
#!/usr/bin/perl
#
use strict;
use File::Slurp;

my $inputfile = @ARGV[0];
my $logfilecontent = read_file($inputfile);
binmode(STDOUT, ":utf8");

You would have the same issue with cat /var/log/x

Adding the binmode(OUTFILE, ":utf8"); fixes your primary report.

Please open a new bug for this enhancement, as it a different issue.

This confirms that binmode utf8 is needed to print out the full ASCII range.

Bug#849531: [Logwatch-devel] Bug#849531: Possible security problem,new logwatch sends mails with charset UTF-8

2016-12-30 Thread Jason Pyeron
I have opened https://sourceforge.net/p/logwatch/bugs/56/ .

I am working a test case for this right now.

As I see it, there are 3 paths to test.

Output as STDOUT, file, and email. In each case does an 8bit value (0x00..0xff 
unsigned) result in a valid UTF-8 character.

Is binmode(STDOUT, ":utf8") needed? Does it fix the issue if it was needed?

Changed encoding to UTF-8, as suggested by Goran Uddeborg.
