=item DESCRIPTION

=over 4

=item Important Caveats

Safest if you C<use feature 'unicode_strings'>, Input and Output Layers,
You must convert your non-ASCII, non-UTF-8 Perl scripts to be UTF-8, C<use
utf8> still needed to enable L<UTF-8|perlunicode/Unicode Encodings> in
scripts, L<UTF-16|perlunicode/Unicode Encodings> scripts autodetected

=item Byte and Character Semantics

=item ASCII Rules versus Unicode Rules

When the string has been upgraded to UTF-8, There are additional methods
for regular expression patterns

=item Extended Grapheme Clusters (Logical characters)

=item Unicode Character Properties

B<C<\p{All}>>, B<C<\p{Alnum}>>, B<C<\p{Any}>>, B<C<\p{ASCII}>>,
B<C<\p{Assigned}>>, B<C<\p{Blank}>>, B<C<\p{Decomposition_Type:
Non_Canonical}>>    (Short: C<\p{Dt=NonCanon}>), B<C<\p{Graph}>>,
B<C<\p{HorizSpace}>>, B<C<\p{In=*}>>, B<C<\p{PerlSpace}>>,

B<C<\p{Titlecase}>>, B<C<\p{Unicode}>>, B<C<\p{VertSpace}>>,

=item Character Encodings for Input and Output

=item Unicode Regular Expression Support Level

[1] C<\N{U+...}> and C<\x{...}>, [2] C<\p{...}> C<\P{...}>.  This
requirement is for a minimal list of properties.  Perl supports these.	See
R2.7 for other properties, [3], [4], [5] C<\b> C<\B> meet most, but not
all, the details of this requirement, but C<\b{wb}> and C<\B{wb}> do, as
well as the stricter R2.3, [6], [7], [8] UTF-8/UTF-EBDDIC used in Perl
allows not only C<U+10000> to C<U+10FFFF> but also beyond C<U+10FFFF>, [9]
Unicode has rewritten this portion of UTS#18 to say that getting canonical
equivalence (see UAX#15 L<"Unicode Normalization
Forms"|https://www.unicode.org/reports/tr15>) is basically to be done at
the programmer level.  Use NFD to write both your regular expressions and
text to match them against (you can use L<Unicode::Normalize>), [10] Perl
has C<\X> and C<\b{gcb}>.  Unicode has retracted their "Grapheme Cluster
Mode", and recently added string properties, which Perl does not yet
support, [11] see L<UAX#29 "Unicode Text
Segmentation"|https://www.unicode.org/reports/tr29>,, [12] see
L<perlunicode/Wildcards in Property Values> above, [13] Perl supports all
the properties in the Unicode Character Database (UCD).  It does not yet
support the listed properties that come from other Unicode sources, [14]
The only optional property that Perl supports is Named Sequence.  None of
these properties are in the UCD

=item Q and A

=over 4

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

=item What character encodings does Perl support?

=item Which version of perl should I use?

=item What about binary data, like images?

=item When should I decode or encode?

=item What if I don't decode?

=item What if I don't encode?

If the string's characters are all code point 255 or lower, Perl outputs
bytes that match those code points. This is what happens with encoded
strings. It can also, though, happen with unencoded strings that happen to
be all code point 255 or lower, Otherwise, Perl outputs the string encoded
as UTF-8. This only happens with strings you neglected to encode. Since
that should not happen, Perl also throws a "wide character" warning in this
case

=item Is there a way to automatically decode or encode?

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

=item Can I use Unicode in my Perl sources?

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

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

=item Why do some characters not uppercase or lowercase correctly?

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

=item How do I convert from encoding FOO to encoding BAR?

=item What is an "IV"?

=item Working with SVs

C<SvIV(SV*)> (C<IV>) and C<SvUV(SV*)> (C<UV>), C<SvNV(SV*)> (C<double>),
Strings are a bit complicated:, Byte string: C<SvPVbyte(SV*, STRLEN len)>
or C<SvPVbyte_nolen(SV*)>, UTF-8 string: C<SvPVutf8(SV*, STRLEN len)> or
C<SvPVutf8_nolen(SV*)>, You can also use C<SvPV(SV*, STRLEN len)> or
C<SvPV_nolen(SV*)> to fetch the SV's raw internal buffer. This is tricky,
though; if your Perl string is C<"\xff\xff">, then depending on the SV's
internal encoding you might get back a 2-byte B<OR> a 4-byte C<char*>.
Moreover, if it's the 4-byte string, that could come from either Perl
C<"\xff\xff"> stored UTF-8 encoded, or Perl C<"\xc3\xbf\xc3\xbf"> stored as
raw octets. To differentiate between these you B<MUST> look up the SV's
UTF8 bit (cf. C<SvUTF8>) to know whether the source Perl string is 2
characters (C<SvUTF8> would be on) or 4 characters (C<SvUTF8> would be off)

B<August 2015>, Port to Perl 5.22, Add handling of NIL: to afstat(), Fix
inheritance of environment variables by subprocesses, Fix exec, and exit in
"forked" subprocesses, Fix issue with newlib's unlink, which could cause
infinite loops, Add flock() emulation using IDOS->LockRecord thanks to Tony
Cook for the suggestion, Fix issue where kill was using the wrong kind of
process ID, B<27th November 2013>, Create new installation system based on
installperl links and Amiga protection bits now set correctly, Pod now
defaults to text, File::Spec should now recognise an Amiga style absolute
path as well as an Unix style one. Relative paths must always be Unix
style, B<20th November 2013>, Configured to use SDK:Local/C/perl to start
standard scripts, Added Amiga::Exec module with support for Wait() and
AmigaOS signal numbers, B<10th October 13>

=item 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?

=item CAVEATS

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

MakeMaker

=over 4

=item DESCRIPTION

=over 4

=item 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?, How
can I organize tests into subdirectories and have them run?, PREFIX vs
INSTALL_BASE from Module::Build::Cookbook, Generating *.pm files with
substitutions eg of $VERSION

=item Common errors and problems

"No rule to make target `/usr/lib/perl5/CORE/config.h', needed by
`Makefile'"

=item 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

=item Module Writing

How do I keep my $VERSION up to date without resetting it manually?, What's
this F<META.yml> thing and how did it get in my F<MANIFEST>?!, How do I
delete everything not in my F<MANIFEST>?, Which tar should I use on
Windows?, Which zip should I use on Windows for '[ndg]make zipdist'?

=item 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?, XSMULTI, Separate directories, Bootstrapping

=item SYNOPSIS

=item 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

=item 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 C<jobs> in
your Harness object

of Test2 from load to finish.

=over 4

=item DESCRIPTION

=item WHAT HAPPENS WHEN I LOAD THE API?

A singleton instance of Test2::API::Instance is created, Several API
functions are defined that use the singleton instance, Then what?

=item WHAT HAPPENS WHEN I USE A TOOL?

A tool function is run, The tool acquires a context object, The tool uses
the context object to create, send, and return events, When done the tool
MUST release the context, The tool returns

=item WHAT HAPPENS WHEN I ACQUIRE A CONTEXT?

$!, $@, $? and $^E are captured and preserved, The API state is changed to
'loaded', The current hub is found, Context acquire hooks fire, Any
existing context is found, Stack depth is measured, A new context is
created (if no existing context was found), Context init hooks fire (if no
existing context was found), $!, $@, $?, and $^E are restored, The context
is returned

=item WHAT HAPPENS WHEN I SEND AN EVENT?

The Test2::Event::Ok module is loaded, A new instance of Test2::Event::Ok
is created, The event object is sent to the hub, The hub runs the event
through any filters, The global test state is updated to reflect the event,
The event is sent to the formatter, The event is sent to all listeners

=item WHAT HAPPENS WHEN I RELEASE A CONTEXT?

The current context clone is released, If this was the canonical context,
it will actually release, Release hooks are called, The context is cleared,
$!, $@, $?, and $^E are restored

=item WHAT HAPPENS WHEN I USE done_testing()?

Any pending IPC events will be culled, Follow-up hooks are run, The final
plan event is generated and processed, The current hub is finalized

=item WHAT HAPPENS WHEN A TEST SCRIPT IS DONE?

API Versions are checked, Any remaining context objects are cleaned up,
Child processes are sent a 'waiting' event, The script will wait for all
child processes and/or threads to complete, The hub stack is cleaned up,
The root hub is finalized, Exit callbacks are called, The scripts exit
value ($?) is set, Broken module diagnostics
