I18N::Charset - IANA Character Set Registry names and Unicode::MapUTF8
(et al.) conversion scheme names

=head1 SYNOPSIS

  use I18N::Charset;

  $sCharset = iana_charset_name('WinCyrillic');
  # $sCharset is now 'windows-1251'
  $sCharset = umap_charset_name('Adobe DingBats');
  # $sCharset is now 'ADOBE-DINGBATS' which can be passed to Unicode::Map->new()
  $sCharset = map8_charset_name('windows-1251');
  # $sCharset is now 'cp1251' which can be passed to Unicode::Map8->new()
  $sCharset = umu8_charset_name('x-sjis');
  # $sCharset is now 'sjis' which can be passed to Unicode::MapUTF8->new()
  $sCharset = libi_charset_name('x-sjis');
  # $sCharset is now 'MS_KANJI' which can be passed to `iconv -f $sCharset ...`
  $sCharset = enco_charset_name('Shift-JIS');
  # $sCharset is now 'shiftjis' which can be passed to Encode::from_to()

=head1 DESCRIPTION

The C module provides access to the IANA Character Set
Registry names for identifying character encoding schemes.  It also
provides a mapping to the character set names used by the
Unicode::Map and Unicode::Map8 modules.

So, for example, if you get an HTML document with a META CHARSET="..."
tag, you can fairly quickly determine what Unicode::MapXXX module can
be used to convert it to Unicode.

If you don't have the module Unicode::Map installed, the umap_
functions will always return undef.
If you don't have the module Unicode::Map8 installed, the map8_
functions will always return undef.
If you don't have the module Unicode::MapUTF8 installed, the umu8_
functions will always return undef.
If you don't have the iconv library installed, the libi_
functions will always return undef.
If you don't have the Encode module installed, the enco_
functions will always return undef.

=head1 CONVERSION ROUTINES

There are four main conversion routines: C,
C, C, and
C.

=over 4

=item iana_charset_name()

This function takes a string containing the name of a character set
and returns a string which contains the official IANA name of the
character set identified. If no valid character set name can be
identified, then C will be returned.  The case and punctuation
within the string are not important.

=head1 CHARACTER SET NAME ALIASING

This module supports several semi-private routines for specifying
character set name aliases.

=over 4

=item  add_iana_alias()

This function takes two strings: a new alias, and a target IANA
Character Set Name (or another alias).  It defines the new alias to
refer to that character set name (or to the character set name to
which the second alias refers).

Returns the target character set name of the successfully installed alias.
Returns 'undef' if the target character set name is not registered.
Returns 'undef' if the target character set name of the second alias
is not registered.

  I18N::Charset::add_iana_alias('my-alias1' => 'Shift_JIS');

With this code, "my-alias1" becomes an alias for the existing IANA
character set name 'Shift_JIS'.

  I18N::Charset::add_iana_alias('my-alias2' => 'sjis');

With this code, "my-alias2" becomes an alias for the IANA character set
name referred to by the existing alias 'sjis' (which happens to be 'Shift_JIS').

=cut

sub add_iana_alias
  {
  my ($sAlias, $sReal) = @_;
  # print STDERR " + add_iana_alias($sAlias, $sReal)\n";

    } # if
  my $mib = _short_to_mib(_strip($sName));
  # print STDERR " --> $sName --> $mib\n";
  $hsMIBofShortname{_strip($sAlias)} = $mib;
  return $sName;
  } # add_iana_alias

#-----------------------------------------------------------------------

=item  add_map8_alias()

This function takes two strings: a new alias, and a target
Unicode::Map8 Character Set Name (or an existing alias to a Map8 name).
It defines the new alias to refer to that mapping name (or to the
mapping name to which the second alias refers).

If the first argument is a registered IANA character set name, then
all aliases of that IANA character set name will end up pointing to
the target Map8 mapping name.

Returns the target mapping name of the successfully installed alias.
Returns 'undef' if the target mapping name is not registered.
Returns 'undef' if the target mapping name of the second alias
is not registered.

  I18N::Charset::add_map8_alias('normal' => 'ANSI_X3.4-1968');

With the above statement, "normal" becomes an alias for the existing
Unicode::Map8 mapping name 'ANSI_X3.4-1968'.

  I18N::Charset::add_map8_alias('normal' => 'US-ASCII');

With the above statement, "normal" becomes an alias for the existing
Unicode::Map mapping name 'ANSI_X3.4-1968' (which is what "US-ASCII"
is an alias for).

  I18N::Charset::add_map8_alias('IBM297' => 'EBCDIC-CA-FR');

With the above statement, "IBM297" becomes an alias for the existing
Unicode::Map mapping name 'EBCDIC-CA-FR'.  As a side effect, all the
aliases for 'IBM297' (i.e. 'cp297' and 'ebcdic-cp-fr') also become
aliases for 'EBCDIC-CA-FR'.

=item  add_libi_alias()

This function takes two strings: a new alias, and a target iconv
Character Set Name (or existing iconv alias).  It defines the new
alias to refer to that character set name (or to the character set
name to which the existing alias refers).

Returns the target conversion scheme name of the successfully installed alias.
Returns 'undef' if there is no such target conversion scheme or alias.

Examples:

  I18N::Charset::add_libi_alias('my-chinese1' => 'CN-GB');

With this code, "my-chinese1" becomes an alias for the existing iconv
conversion scheme 'CN-GB'.

  I18N::Charset::add_libi_alias('my-chinese2' => 'EUC-CN');

With this code, "my-chinese2" becomes an alias for the iconv
conversion scheme referred to by the existing alias 'EUC-CN' (which
happens to be 'CN-GB').

=item  add_enco_alias()

This function takes two strings: a new alias, and a target Encode
encoding Name (or existing Encode alias).  It defines the new alias
referring to that encoding name (or to the encoding to which the
existing alias refers).

Returns the target encoding name of the successfully installed alias.
Returns 'undef' if there is no such encoding or alias.

Examples:

  I18N::Charset::add_enco_alias('my-japanese1' => 'jis0201-raw');

With this code, "my-japanese1" becomes an alias for the existing
encoding 'jis0201-raw'.

  I18N::Charset::add_enco_alias('my-japanese2' => 'my-japanese1');

With this code, "my-japanese2" becomes an alias for the encoding
referred to by the existing alias 'my-japanese1' (which happens to be
'jis0201-raw' after the previous call).

=head1 KNOWN BUGS AND LIMITATIONS

=over 4

=item *

There could probably be many more aliases added (for convenience) to
all the IANA names.
If you have some specific recommendations, please email the author!

=item *

The only character set names which have a corresponding mapping in the
Unicode::Map8 module are the character sets that Unicode::Map8 can
convert.

Similarly, the only character set names which have a corresponding
mapping in the Unicode::Map module are the character sets that
Unicode::Map can convert.

=item *

In the current implementation, all tables are read in and initialized
when the module is loaded, and then held in memory until the program
exits.  A "lazy" implementation (or a less-portable tied hash) might
lead to a shorter startup time.  Suggestions, patches, comments are
always welcome!

=back

=head1 SEE ALSO

=over 4

=item Unicode::Map

Convert strings from various multi-byte character encodings to and from Unicode.

=item Unicode::Map8

Convert strings from various 8-bit character encodings to and from Unicode.

=item Jcode

Convert strings among various Japanese character encodings and Unicode.

=item Unicode::MapUTF8

A wrapper around all three of these character set conversion distributions.

    Character Sets

    Expert Review
    Ned Freed (primary), Martin Dürst (secondary)
    These are the official names for character sets that may be used in
the Internet and may be referred to in Internet documentation.  These
names are expressed in ANSI_X3.4-1968 which is commonly called
US-ASCII or simply ASCII.  The character set most commonly use in the
Internet and used especially in protocol standards is US-ASCII, this
is strongly encouraged.  The use of the name US-ASCII is also
encouraged.

The character set names may be up to 40 characters taken from the
printable characters of US-ASCII.  However, no distinction is made
between use of upper and lower case letters.

The MIBenum value is a unique value for use in MIBs to identify coded
character sets.

The value space for MIBenum values has been divided into three
regions. The first region (3-999) consists of coded character sets
that have been standardized by some standard setting organization.
This region is intended for standards that do not have subset
implementations. The second region (1000-1999) is for the Unicode and
ISO/IEC 10646 coded character sets together with a specification of a
(set of) sub-repertoires that may occur.  The third region (>1999) is
intended for vendor specific coded character sets.

        Assigned MIB enum Numbers
        -------------------------
        0-2             Reserved
        3-999           Set By Standards Organizations
        1000-1999       Unicode / 10646
        2000-2999       Vendor

The aliases that start with "cs" have been added for use with the
IANA-CHARSET-MIB as originally defined in , and as currently
maintained by IANA at .
Note that the ianacharset-mib needs to be kept in sync with this
registry.  These aliases that start with "cs" contain the standard
numbers along with suggestive names in order to facilitate applications
that want to display the names in user interfaces.  The "cs" stands
for character set and is provided for applications that need a lower
case first letter but want to use mixed case thereafter that cannot
contain any special characters, such as underbar ("_") and dash ("-").

If the character set is from an ISO standard, its cs alias is the ISO
standard number or name.  If the character set is not from an ISO
standard, but is registered with ISO (IPSJ/ITSCJ is the current ISO
Registration Authority), the ISO Registry number is specified as
ISOnnn followed by letters suggestive of the name or standards number
of the code set.  When a national or international standard is
revised, the year of revision is added to the cs alias of the new
character set entry in the IANA Registry in order to distinguish the
revised character set from the original character set.
