NAME Encode::ISO2022 - ISO/IEC 2022 character encoding scheme SYNOPSIS package FooEncoding; use Encode::ISO2022; our @ISA = qw(Encode::ISO2022); $Encode::Encoding{'foo-encoding'} = bless { Name => 'foo-encoding', CCS => [ {...CCS #1...}, {...CCS #2...}, ....] } => __PACKAGE__; DESCRIPTION This module provides a character encoding scheme (CES) switching a set of multiple coded character sets (CCS). Instances of Encode::ISO2022 have following hash items. Name => STRING The name of this encoding as Encode::Encoding object. CCS => [ FEATURE, FEATURE, ...] List of features defining CCSs used by this encoding. Each item is a hash reference containing following items. bytes => NUMBER Number of bytes to represent each character. Default is 1. dec_only => BOOLEAN If true value is set, this CCS will be used only for decoding. encoding => ENCODING Encode::Encoding object used as CCS. Mandatory. Encodings used for CCS must provide "raw" conversion. Namely, they must be stateless and fixed-length conversion over 94^n or 96^n code tables. Encode::ISO2022::CCS lists available CCSs. gr => BOOLEAN If true value is set, each character will be invoked to GR. g => STRING g_init => STRING Working set this CCS may be designated to: 'g0', 'g1', 'g2' or 'g3'. If "g_init" is set, this CCS will be designated at beginning of coversion implicitly, and at end of conversion explicitly. If "g" or "g_init" is set and neither of "ls" nor "ss" is not set, this CCS will be invoked when it is designated. If neither of "g", "g_init", "ls" nor "ss" is set, this CCS is invoked always. g_seq => STRING Escape sequence to designate this CCS, if it can be designated explicitly. ls => STRING ss => STRING Escape sequence or control character to invoke this CCS, if it should be invoked explicitly. If "ss" is set, this CCS will be invoked for only one character. LineInit => BOOLEAN If it is true, designation and invokation states will be initialized at beginning of lines. SubChar => STRING Unicode string to be used for substitution character. To know more about use of this module, the source of Encode::ISO2022JP2 may be an example.
