Re^3: i18n/utf8 problem, 'utf8 "\xF8" does not map to Unicode'

If you have the raw bytestring, the easiest way to see if it's valid UTF-8 is to decode it to a unicode string. If that fails, it wasn't utf8 enough :)

utf8::decode($string)
    or die "Input is not valid UTF-8";
[download]

utf8::decode(my $text = $binary)
    or die "Input is not valid UTF-8";
[download]

If you leave out the "or die" clause, any invalid UTF-8 will just be seen as ISO-8859-1.

Update: changed the examples as per ikegami's sound response.

That should be `utf8::decode(my $text = $binary) or die "Input is not valid UTF-8";` [download] It works in-place.	[reply] [d/l]
