NAME
Lingua::Translit - transliterates text between writing systems
SYNOPSIS
use Lingua::Translit;
my $tr = new Lingua::Translit("ISO 843");
my $text_tr = $tr->translit("character oriented string");
if ($tr->can_reverse()) {
$text_tr = $tr->translit_reverse("character oriented string");
}
DESCRIPTION
Lingua::Translit can be used to convert text from one writing system to another, based on
national or international transliteration tables. Where possible a reverse
transliteration is supported.
The term "transliteration" describes the conversion of text from one writing system or
alphabet to another one. The conversion is ideally unique, mapping one character to
exactly one character, so the original spelling can be reconstructed. Practically this is
not always the case and one single letter of the original alphabet can be transcribed as
two, three or even more letters.
Furthermore there is more than one transliteration scheme for one writing system.
Therefore it is an important and necessary information, which scheme will be or has been
used to transliterate a text, to work integrative and be able to reconstruct the original
data.
Reconstruction is a problem though for non-unique transliterations, if no language
specific knowledge is available as the resulting clusters of letters may be ambiguous.
For example, the Greek character "PSI" maps to "ps", but "ps" could also result from the
sequence "PI", "SIGMA" since "PI" maps to "p" and "SIGMA" maps to s. If a transliteration
table leads to ambiguous conversions, the provided table cannot be used reverse.
Otherwise the table can be used in both directions, if appreciated. So if ISO 9 is
originally created to convert Cyrillic letters to the Latin alphabet, the reverse
transliteration will transform Latin letters to Cyrillic.
METHODS
new("name of table")
Initializes an object with the specific transliteration table, e.g. "ISO 9".
translit("character oriented string")
Transliterates the given text according to the object's transliteration table. Returns
the transliterated text.
translit_reverse("character oriented string")
Transliterates the given text according to the object's transliteration table, but uses it
the other way round. For example table ISO 9 is a transliteration scheme for the
conversion of Cyrillic letters to the Latin alphabet. So if used reverse, Latin letters
will be mapped to Cyrillic ones.
Returns the transliterated text.
can_reverse()
Returns true (1), iff reverse transliteration is possible. False (0) otherwise.
name()
Returns the name of the chosen transliteration table, e.g. "ISO 9".
desc()
Returns a description for the transliteration, e.g. "ISO 9:1995, Cyrillic to Latin".

ADDING NEW TRANSLITERATIONS
In case you want to add your own transliteration tables to Lingua::Translit, have a look
at the developer documentation at
<https://www.netzum-sorglos.de/software/lingua-translit/developer-documentation.html>.
A template of a transliteration table is provided as well (xml/template.xml) so you can
easily start developing.
RESTRICTIONS
Lingua::Translit is suited to handle Unicode and utilizes comparisons and regular
expressions that rely on code points. Therefore, any input is supposed to be character
oriented ("use utf8;", ...) instead of byte oriented.
However, if your data is byte oriented, be sure to pass it UTF-8 encoded to translit()
and/or translit_reverse() - it will be converted internally.
BUGS
None known.
