NAME
Unicode::MapUTF8 - Conversions to and from arbitrary character sets and UTF8
SYNOPSIS
use Unicode::MapUTF8 qw(to_utf8 from_utf8 utf8_supported_charset);
# Convert a string in 'ISO-8859-1' to 'UTF8'
my $output = to_utf8({ -string => 'An example', -charset => 'ISO-8859-1' });
# Convert a string in 'UTF8' encoding to encoding 'ISO-8859-1'
my $other = from_utf8({ -string => 'Other text', -charset => 'ISO-8859-1' });
# List available character set encodings
my @character_sets = utf8_supported_charset;
# Convert between two arbitrary (but largely compatible) charset encodings
# (SJIS to EUC-JP)
my $utf8_string = to_utf8({ -string =>$sjis_string, -charset => 'sjis'});
my $euc_jp_string = from_utf8({ -string => $utf8_string, -charset => 'euc-jp' })
# Verify that a specific character set is supported
if (utf8_supported_charset('ISO-8859-1') {
# Yes
}
DESCRIPTION
Provides an adapter layer between core routines for converting to and from UTF8 and other encodings. In essence, a way to give multiple existing Unicode modules a single common interface so you don't have to know the underlaying implementations to do simple UTF8 to-from other character set encoding conversions. As such, it wraps the Unicode::String, Unicode::Map8, Unicode::Map and Jcode modules in a standardized and simple API.
This also provides general character set conversion operation based on UTF8 - it is possible to convert between any two compatible and supported character sets via a simple two step chaining of conversions.
As with most things Perlish - if you give it a few big chunks of text to chew on instead of lots of small ones it will handle many more characters per second.
By design, it can be easily extended to encompass any new charset encoding conversion modules that arrive on the scene.
CHANGES
1.05 2000.10.23 - Error in conversions from UTF8 to multibyte encodings corrected
1.04 2000.10.23 - Additional diagnostic messages added for internal error conditions
1.03 2000.10.22 - Bug fix for load time autodetction of Unicode::Map8 encodings
1.02 2000.10.22 - Added load time autodetection of Unicode::Map8 supported character set encodings.
Fixed internal calling error for some character sets with 'from_utf8'.
Thanks goes to Ilia Lobsanov <ilia@lobsanov.com> for reporting the
problem.
1.01 2000.10.02 - Fixed handling of empty strings and added more identification for error messages.
1.00 2000.09.29 - Pre-release version
FUNCTIONS
utf8_supported_charset($charset_name);
-
Returns true if the named charset is supported. false if it is not.
Example:
if (! utf8_supported_charset('VISCII')) { # No support yet }
If called in a list context with no parameters, it will return a list of all supported character set names.
Example:
my @charsets = utf8_supported_charset;
to_utf8({ -string =
$string, -charset => $source_charset });>-
Returns the string converted to UTF8 from the specified source charset.
from_utf8({ -string =
$string, -charset => $target_charset});>-
Returns the string converted from UTF8 to the specified target charset.
