MARC::Charset::Table - character mapping db
use MARC::Charset::Table; use MARC::Charset::Constants qw(:all); # create the table object my $table = MARC::Charset::Table->new(); # get a code using the marc8 character set code and the character my $code = $table->lookup_by_marc8(CYRILLIC_BASIC, 'K'); # get a code using the utf8 value $code = $table->lookup_by_utf8(chr(0x043A));
MARC::Charset::Table is a wrapper around the character mapping database, which is implemented as a tied hash on disk. This database gets generated by Makefile.PL on installation of MARC::Charset using MARC::Charset::Compiler.
The database is essentially a key/value mapping where a key is a MARC-8 character set code + a MARC-8 character, or an integer representing the UCS code point. These keys map to a serialized MARC::Charset::Code object.
Add a MARC::Charset::Code to the table.
Retrieve a code using a hash key.
Looks up MARC::Charset::Code entry using a character set code and a MARC-8 value.
use MARC::Charset::Constants qw(HEBREW); $code = $table->lookup_by_marc8(HEBREW, chr(0x60));
Looks up a MARC::Charset::Code object using a utf8 value.
Returns a reference to a tied character database. MARC::Charset::Table wraps access to the db, but you can get at it if you want.
Returns the path to the character encoding database. Can be called statically too:
An alternate constructor which removes the existing database and starts afresh. Be careful with this one, it's really only used on MARC::Charset installation.
