String::Dump::Debugging - String debugging tips with String::Dump
This document describes String::Dump version 0.09.
This document is a collection of tips for debugging Unicode strings or byte
strings using String::Dump.
When dumping literal strings in your code, use the utf8 pragma when Unicode
strings are desired and donXt use it or disable it when byte strings are
desired. The pragma may also be lexically enabled or disabled.
say dump_hex('Xis! X'); # C4 9C 69 73 21 20 E2 98 BA
say dump_hex('Xis! X'); # 11C 69 73 21 20 263A
The simplest way to ensure that youXre working with Unicode strings from all of
your basic sources of input is to use the utf8::all pragma. This extends the
utf8 pragma to automatically convert command-line arguments provided by @ARGV,
user-defined filehandles, as well as standard filehandles like
"STDIN", among others.
To handle strings provided by other sources of input, such as from network
protocols or web requests, decode the byte string to a Unicode string via
Encode::decode using the source encoding name as the first argument.
use Encode qw( decode );
say dump_hex( decode('UTF-8', $string) );
