Re^4: HTML::Entities and Unicode quotes

Ack! Please don't use that. It does NOT indicate whether something has been decoded or not. You have been misinformed.

Yes, I saw that after I posted. Got distracted mid-post and when I got back didn't revisit the node to see the new replies.

It's the UTF-8 encoding of U+201D RIGHT DOUBLE QUOTATION MARK.

is_utf8 is even misleadingly named. I'd have called it "needs_utf8". But I won't use it.

Regarding

use open ':encoding(utf8)';

in my earlier traversal of perlunifaq I saw

Using :utf8 for input can sometimes result in security breaches, so please use :encoding(UTF-8) instead.

in the answer to What is the difference between :encoding and :utf8? Is ':encoding(utf8)' the same as ':encoding(UTF-8)'?

is_utf8 is even misleadingly named. I'd have called it "needs_utf8". As in needs to be encoded using UTF-8? No, it doesn't indicate a need for the string to be encoded, using UTF-8 or otherwise. It is actually accurately named, but refers to how the string is stored internally, not the content of the string. Is ':encoding(utf8)' the same as ':encoding(UTF-8)'? The encoding is called UTF-8, so use "UTF-8" (case doesn't matter). I don't know how `:encoding(utf8)` is different, but I don't see any reason for figuring it out.	[reply] [d/l]
