Re: Why won't Perl convert (Latin1 | ISO-8859-1) to (UTF-8 | utf8)?

in reply to Why won't Perl convert (Latin1 | ISO-8859-1) to (UTF-8 | utf8)?

How are you determining what encoding is used by the end file? If you're loading them into a web browser then the content type will be determined by the meta information. AFAIK the content type of a text file is what you say it is, not detected.
If you spot any bugs in my solutions, it's because I've deliberately left them in as an exercise for the reader! :-)

[Eily]: you could tie a variable into not having the same value each time, if you like to make people who try to debug your code facepalm
[Corion]: perl -wle 'package o; use overload q("") => sub {warn "str"; ""}, bool => sub{warn "bool"; 1}; package main; my $o={}; bless $o => o; print "Yay" if ($o && !length($o))'
[Corion]: But people writing such code should document the objects they construct and why it makes sense for an object to be invisible as string while being true in a boolean context
[hippo]: That's equal parts clever and horrendous.
[Eily]: the overload version wouldn't return true with "$x" && !length $x though, I guess
[hippo]: The more I look at this code, the more $x is a plain old scalar and the more this condition will never be true. I'm calling it a bug at this point.
[hippo]: Thanks for your input which has soothed my sanity (a little)
[Corion]: Eily: Sure - if you force both things into stringy things, then you break that magic. But that would also mean that you changed the expression, as now $x = 0.00 will be true instead of false as it were before
[Corion]: Ah no, at least in my feeble experiments that doesn't change the meaning
[Corion]: We sell sanity in small packages ;)
