perlunicode - Unicode support in Perl

DESCRIPTION
Important Caveats
Safest if you "use feature 'unicode_strings'", Input and Output Layers, You should convert your non-ASCII, non-UTF-8 Perl scripts to be UTF-8, "use utf8" still needed to enable UTF-8 in scripts, "BOM"-marked scripts and UTF-16 scripts autodetected
Byte and Character Semantics
ASCII Rules versus Unicode Rules
When the string has been upgraded to UTF-8, There are additional methods for regular expression patterns
Extended Grapheme Clusters (Logical characters)
Unicode Character Properties
"\p{All}", "\p{Alnum}", "\p{Any}", "\p{ASCII}", "\p{Assigned}", "\p{Blank}", "\p{Decomposition_Type: Non_Canonical}" (Short: "\p{Dt=NonCanon}"), "\p{Graph}", "\p{HorizSpace}", "\p{In=*}", "\p{PerlSpace}", "\p{PerlWord}", "\p{Posix...}", "\p{Present_In: *}" (Short: "\p{In=*}"), "\p{Print}", "\p{SpacePerl}", "\p{Title}" and "\p{Titlecase}", "\p{Unicode}", "\p{VertSpace}", "\p{Word}", "\p{XPosix...}"
User-Defined Character Properties
User-Defined Case Mappings (for serious hackers only)
Character Encodings for Input and Output
Unicode Regular Expression Support Level
[1] "\N{U+...}" and "\x{...}", [2] "\p{...}" "\P{...}", [3] supports not only minimal list, but all Unicode character properties (see Unicode Character Properties above), [4] "\d" "\D" "\s" "\S" "\w" "\W" "\X" "[:prop:]" "[:^prop:]", [5] The experimental feature starting in v5.18 "(?[...])" accomplishes this, [6] "\b" "\B", [7] Note that Perl does Full case-folding in matching, not Simple:, [8] Perl treats "\n" as the start- and end-line delimiter. Unicode specifies more characters that should be so-interpreted, [9] But "qr/\b{lb}/" and "Unicode::LineBreak" are available, [10] UTF-8/UTF-EBDDIC used in Perl allows not only "U+10000" to "U+10FFFF" but also beyond "U+10FFFF"

perlunifaq - Perl Unicode FAQ

Q and A

perlunitut isn't really a Unicode tutorial, is it?

What character encodings does Perl support?

Which version of perl should I use?

What about binary data, like images?

When should I decode or encode?

What if I don't decode?

What if I don't encode?

Is there a way to automatically decode or encode?

What if I don't know which encoding was used?

Can I use Unicode in my Perl sources?

Data::Dumper doesn't restore the UTF8 flag; is it broken?

Why do regex character classes sometimes match only in the ASCII range?

Why do some characters not uppercase or lowercase correctly?

How can I determine if a string is a text string or a binary string?

How do I convert from encoding FOO to encoding BAR?

What are "decode_utf8" and "encode_utf8"?

What is a "wide character"?

INTERNALS

What is "the UTF8 flag"?

What about the "use bytes" pragma?

What about the "use encoding" pragma?

What is the difference between ":encoding" and ":utf8"?

What's the difference between "UTF-8" and "utf8"?

I lost track; what encoding is the internal format really?

What's the minimum perl version required to run Archive::Tar?, Isn't Archive::Tar slow?, Isn't Archive::Tar heavier on memory than /bin/tar?, Can you lazy-load data instead?, How much memory will an X kb tar file need?, What do you do with unsupported filetypes in an archive?, I'm using WinZip, or some other non-POSIX client, and files are not being extracted properly!, How do I extract only files that have property X from an archive?, How do I access .tar.Z files?, How do I handle Unicode strings?

ExtUtils::MakeMaker::Config - Wrapper around Config.pm

SYNOPSIS

DESCRIPTION

ExtUtils::MakeMaker::FAQ - Frequently Asked Questions About MakeMaker

DESCRIPTION
Module Installation
How do I install a module into my home directory?, How do I get MakeMaker and Module::Build to install to the same place?, How do I keep from installing man pages?, How do I use a module without installing it?, PREFIX vs INSTALL_BASE from Module::Build::Cookbook
Common errors and problems
"No rule to make target `/usr/lib/perl5/CORE/config.h', needed by `Makefile'"
Philosophy and History
Why not just use <insert other build config tool here>?, What is Module::Build and how does it relate to MakeMaker?, pure perl. no make, no shell commands, easier to customize, cleaner internals, less cruft
Module Writing
How do I keep my $VERSION up to date without resetting it manually?, What's this META.yml thing and how did it get in my MANIFEST?!, How do I delete everything not in my MANIFEST?, Which tar should I use on Windows?, Which zip should I use on Windows for '[nd]make zipdist'?
XS
How do I prevent "object version X.XX does not match bootstrap parameter Y.YY" errors?, How do I make two or more XS files coexist in the same directory?

Obtaining and installing libnet

What is libnet ?

Which version of perl do I need ?

What other modules do I need ?

What machines support libnet ?

Where can I get the latest libnet release

Using Net::FTP

How do I download files from an FTP server ?

How do I transfer files in binary mode ?

How can I get the size of a file on a remote FTP server ?

How can I get the modification time of a file on a remote FTP server ?

How can I change the permissions of a file on a remote server ?

Can I do a reget operation like the ftp command ?

How do I get a directory listing from an FTP server ?

Changing directory to "" does not fail ?

I am behind a SOCKS firewall, but the Firewall option does not work ?

I am behind an FTP proxy firewall, but cannot access machines outside ?

My ftp proxy firewall does not listen on port 21

Is it possible to change the file permissions of a file on an FTP server ?

I have seen scripts call a method message, but cannot find it documented ?

Why does Net::FTP not implement mput and mget methods

Using Net::SMTP

Why can't the part of an Email address after the @ be used as the hostname ?

Why does Net::SMTP not do DNS MX lookups ?

The verify method always returns true ?

Debugging scripts

How can I debug my scripts that use Net::* modules ?

SYNOPSIS
DESCRIPTION
Call Pod::Perldoc::GetOptsOO::getopts($object, \@ARGV, $truth), Given -n, if there's a opt_n_with, it'll call $object->opt_n_with( ARGUMENT ) (e.g., "-n foo" => $object->opt_n_with('foo'). Ditto "-nfoo"), Otherwise (given -n) if there's an opt_n, we'll call it $object->opt_n($truth) (Truth defaults to 1), Otherwise we try calling $object->handle_unknown_option('n') (and we increment the error count by the return value of it), If there's no handle_unknown_option, then we just warn, and then increment the error counter

TAP::Parser::Scheduler - Schedule tests during parallel testing

VERSION
SYNOPSIS
DESCRIPTION
METHODS
Class Methods
Rules data structure
By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one, "First match wins". The first rule that matches a test will be the one that applies, Any test which does not match a rule will be run in sequence at the end of the run, The existence of a rule does not imply selecting a test. You must still specify the tests to run, Specifying a rule to allow tests to run in parallel does not make the run in parallel. You still need specify the number of parallel "jobs" in your Harness object
