marc::charset::code
MARC::Charset::Code(3pm) User Contributed Perl Documentation MARC::Charset::Code(3pm) NAME
MARC::Charset::Code - represents a MARC-8/UTF-8 mapping SYNOPSIS
DESCRIPTION
Each mapping from a MARC-8 value to a UTF-8 value is represented by a MARC::Charset::Code object in a MARC::Charset::Table. METHODS
new() The constructor. name() A descriptive name for the code point. marc() A string representing the MARC-8 bytes codes. ucs() A string representing the UCS code point in hex. charset_code() The MARC-8 character set code. is_combining() Returns true/false to tell if the character is a combining character. to_string() A stringified version of the object suitable for pretty printing. char_value() Returns the unicode character. Essentially just a helper around ucs(). marc_value() The string representing the MARC-8 encoding. charset_name() Returns the name of the character set, instead of the code. to_string() Returns a stringified version of the object. marc8_hash_code() Returns a hash code for this Code object for looking up the object using MARC8. First portion is the character set code and the second is the MARC-8 value. utf8_hash_code() Returns a hash code for uniquely identifying a Code by it's UCS value. default_charset_group Returns 'G0' or 'G1' indicating where the character is typicalling used in the MARC-8 environment. get_marc8_escape Returns an escape sequence to move to the Code from another marc-8 character set. charset_value Returns the charset value, not the hex sequence. perl v5.12.4 2010-03-29 MARC::Charset::Code(3pm)
