How can I convert a Unicode codepoint (\uXXXX) into a character in Perl?
I have some unicode codepoints (\u5315\u4e03\u58ec\u4e8c\u4e0a\u53b6\u4e4b), which I have to convert into actual characters开发者_如何学运维 they represent.
What's the simplest way to do so?
Sometimes I'd just use pack:
binmode STDOUT, ':utf8';
my $string = '\\u5315\\u4e03\\u58ec\\u4e8c\\u4e0a\\u53b6\\u4e4b';
$string =~ s/\\u(....)/ pack 'U*', hex($1) /eg;
print $string;
Could Unicode::Escape be what you need?
perl -C -E'say"\x{5315}\x{4e03}\x{58ec}\x{4e8c}\x{4e0a}\x{53b6}\x{4e4b}"'
or funny way
perl -C -E'say map chr hex, qw(5315 4e03 58ec 4e8c 4e0a 53b6 4e4b)'
use JSON::XS
print JSON::XS->new->decode('{"a":"\u5315\u4e03\u58ec\u4e8c\u4e0a\u53b6\u4e4b"}')->{a}
