Perl编码-英国字符 [英] Perl Encode - UK characters

问题描述

这是来自此问题的第2部分问题

This is a part 2 question from This Question.

所以我正在尝试：encode功能，但是一点运气都没有。

So I'm trying out the :encode functionality but having no luck at all.

use Encode;
use utf8;

# Should print: iso-8859-15
print "Latin-9 Encoding: ".find_encoding("latin9")->name."\n"; 

my $encUK = encode("iso-8859-15", "UK €");
print "Encoded UK: ".$encUK."\n";

结果：

Encoded UK: UK €

结果是否应编码？我在这里做什么错了？

Shouldn't the results be encoded? what am I doing wrong here?

编辑：

添加了建议的内容：

use utf8;

现在我明白了：

Encoded UK: UK �

现在拔出头发：/

推荐答案

不要拉扯头发。您所做的一切正确，已完成，并且已经在获取预期的数据；输出使您感到困惑，因为您可能是从未针对Latin-9设置的终端查看的，而是针对其他编码（大概是UTF-8）的。

Don't pull your hair. You did everything right, are finished and are already getting the intended data; the output is confusing you because you probably look at it from a terminal that is not set up for Latin-9, but for a different encoding, presumably UTF-8.

> perl -e'use utf8; use Encode; print encode "Latin-9", "Euro €"'
Euro �

> perl -e'use utf8; use Encode; print encode "Latin-9", "Euro €"' | hex
0000  45 75 72 6f 20 a4                                 Euro .

代码点A4的确是拉丁文9中的欧元符号。

Codepoint A4 is indeed the Euro symbol in Latin-9.
