NAME

6       Lingua::Translit - transliterates text between writing systems
7

SYNOPSIS

9         use Lingua::Translit;
10
11         my $tr = new Lingua::Translit("ISO 843");
12
13         my $text_tr = $tr->translit("character oriented string");
14
15         if ($tr->can_reverse()) {
16           $text_tr = $tr->translit_reverse("character oriented string");
17         }
18

DESCRIPTION

20       Lingua::Translit can be used to convert text from one writing system to
21       another, based on national or international transliteration tables.
22       Where possible a reverse transliteration is supported.
23
24       The term "transliteration" describes the conversion of text from one
25       writing system or alphabet to another one.  The conversion is ideally
26       unique, mapping one character to exactly one character, so the original
27       spelling can be reconstructed.  Practically this is not always the case
28       and one single letter of the original alphabet can be transcribed as
29       two, three or even more letters.
30
31       Furthermore there is more than one transliteration scheme for one
32       writing system.  Therefore it is an important and necessary
33       information, which scheme will be or has been used to transliterate a
34       text, to work integrative and be able to reconstruct the original data.
35
36       Reconstruction is a problem though for non-unique transliterations, if
37       no language specific knowledge is available as the resulting clusters
38       of letters may be ambiguous.  For example, the Greek character "PSI"
39       maps to "ps", but "ps" could also result from the sequence "PI",
40       "SIGMA" since "PI" maps to "p" and "SIGMA" maps to s.  If a
41       transliteration table leads to ambiguous conversions, the provided
42       table cannot be used reverse.
43
44       Otherwise the table can be used in both directions, if appreciated.  So
45       if ISO 9 is originally created to convert Cyrillic letters to the Latin
46       alphabet, the reverse transliteration will transform Latin letters to
47       Cyrillic.

METHODS

50   new("name of table")
51       Initializes an object with the specific transliteration table, e.g.
52       "ISO 9".
53
54   translit("character oriented string")
55       Transliterates the given text according to the object's transliteration
56       table.  Returns the transliterated text.
57
58   translit_reverse("character oriented string")
59       Transliterates the given text according to the object's transliteration
60       table, but uses it the other way round. For example table ISO 9 is a
61       transliteration scheme for the conversion of Cyrillic letters to the
62       Latin alphabet. So if used reverse, Latin letters will be mapped to
63       Cyrillic ones.
64
65       Returns the transliterated text.
66
67   can_reverse()
68       Returns true (1), iff reverse transliteration is possible.  False (0)
69       otherwise.
70
71   name()
72       Returns the name of the chosen transliteration table, e.g. "ISO 9".
73
74   desc()
75       Returns a description for the transliteration, e.g. "ISO 9:1995,
76       Cyrillic to Latin".

ADDING NEW TRANSLITERATIONS

144       In case you want to add your own transliteration tables to
145       Lingua::Translit, have a look at the developer documentation at
146       <https://www.netzum-sorglos.de/software/lingua-translit/developer-documentation.html>.
147
148       A template of a transliteration table is provided as well
149       (xml/template.xml) so you can easily start developing.
150

RESTRICTIONS

152       Lingua::Translit is suited to handle Unicode and utilizes comparisons
153       and regular expressions that rely on code points.  Therefore, any input
154       is supposed to be character oriented ("use utf8;", ...) instead of byte
155       oriented.
156
157       However, if your data is byte oriented, be sure to pass it UTF-8
158       encoded to translit() and/or translit_reverse() - it will be converted
159       internally.
