in thread Writing HTML file with UTF-8 chars

In the following example, all combinations of two different inputs and output methods are shown. The Arabic string comes in as a sequence of bytes without Perl knowing it should be UTF-8. The French one, on the other hand, is proper UTF-8 (thanks to use utf8; and saving the source as UTF-8). When writing bytes to the output not trying to interpret the bytes, we get the "correct" solution. Similarly for UTF-8 string and UTF-8 output. The other two combinations are wrong.
#!/usr/bin/perl use warnings; use strict; use utf8; my %topurls = (arabic => { title => join(q(), map chr $_, 216, 167, 217, 132, 216, 185, + 216, 177, 216, 168, 217, 138, 216, + 169), count => 42, users => 11, }, french => { title => 'une chèvre goûte des légumes', count => 11, users => 42, } ); open my $OUT, '>', 'topurls.htm' or die "Can't open output: $!"; print $OUT <<'END_HEADER'; <html> <head> <title>Top URLs</title> <meta http-equiv="Content-Type" content="text/html; ch +arset=utf-8"> </head> <body> <h3>Top URLs</h3> <table cellpadding=10 border=1><tr><th>Link</th><th>Co +unt</th><th>Users</th></tr> END_HEADER for my $u (keys %topurls) { my @line; $line[0] = '<a target="_blank" href="'.$u.'">'.$topurls{$u}{title} +.'</a>'; $line[1] = $topurls{$u}{count}; $line[2] = $topurls{$u}{users}; binmode $OUT, ':bytes'; print $OUT '<tr><td>Bytes: ', join('</td><td>', @line), "</td></tr +>\n"; binmode $OUT, ':utf8'; print $OUT '<tr><td>UTF-8: ', join('</td><td>', @line), "</td></tr +>\n"; } print $OUT '</table></body></html>'; close $OUT;

Now you just have to find out what kind of input you have.
