4 Provides a central transliteration service to other Drupal modules, and
5 sanitizes file names while uploading.

15 1. Install as usual, see http://drupal.org/node/70151 for further information.
17 2. If you are installing to an existing Drupal site, you might want to fix
18 existing file names after installation, which will update all file names
19 containing non-ASCII characters. However, if you have manually entered links
20 to those files in any contents, these links will break since the original
21 files are renamed. Therefore it is a good idea to test the conversion
22 first on a copy of your web site. You'll find the retroactive conversion at
23 Configuration and modules >> Media >> File system >> Transliteration.
28 This module doesn't require special permissions.
30 This module can be configured from the File system configuration page
31 (Configuration and modules >> Media >> File system >> Settings).
33 - Transliterate file names during upload: If you need more control over the
34 resulting file names you might want to disable this feature here and install
35 the FileField Paths module (http://drupal.org/project/filefield_paths)
38 - Lowercase transliterated file names: It is recommended to enable this option
39 to prevent issues with case-insensitive file systems.
42 -- 3RD PARTY INTEGRATION --
44 Third party developers seeking an easy way to transliterate text or file names
45 may use transliteration functions as follows:
47 if (function_exists('transliteration_get')) {
48 $transliterated = transliteration_get($text, $unknown, $source_langcode);
51 or, in case of file names:
53 if (function_exists('transliteration_clean_filename')) {
54 $transliterated = transliteration_clean_filename($filename, $source_langcode);
57 Note that the optional $source_langcode parameter specifies the language code
58 of the input. If the source language is not known at the time of transliter-
59 ation, it is recommended to set this argument to the site default language:
61 $output = transliteration_get($text, '?', language_default('language'));
63 Otherwise the current display language will be used, which might produce
67 -- LANGUAGE SPECIFIC REPLACEMENTS --
69 This module supports language specific variations in addition to the basic
70 transliteration replacements. The following guide explains how to add them:
72 1. First find the Unicode character code you want to replace. As an example,
73 we'll be adding a custom transliteration for the cyrillic character 'г'
74 (hexadecimal code 0x0433) using the ASCII character 'q' for Azerbaijani
77 2. Transliteration stores its mappings in banks with 256 characters each. The
78 first two digits of the character code (04) tell you in which file you'll
79 find the corresponding mapping. In our case it is data/x04.php.
81 3. If you open that file in an editor, you'll find the base replacement matrix
82 consisting of 16 lines with 16 characters on each line, and zero or more
83 additional language-specific variants. To add our custom replacement, we need
84 to do two things: first, we need to create a new transliteration variant
85 for Azerbaijani since it doesn't exist yet, and second, we need to map the
86 last two digits of the hexadecimal character code (33) to the desired output
89 $variant['az'] = array(0x33 => 'q');
91 (see http://people.w3.org/rishida/names/languages.html for a list of
94 Any Azerbaijani input will now use the appropriate variant.
96 Also take a look at data/x00.php which already contains a bunch of language
97 specific replacements. If you think your overrides are useful for others please
98 file a patch at http://drupal.org/project/issues/transliteration.

110 UTF-8 normalization is based on UtfNormal.php from MediaWiki
111 (http://www.mediawiki.org) and transliteration uses data from Sean M. Burke's
