## 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?

FAQ

  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?

CAVEATS
TODO

  Check if passed in handles are open for read/write, Allow archives to be passed in as string, Facilitate processing an opened filehandle of a compressed archive

## 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?

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

  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
