# Enable Generic Transliteration

The default IDOL Server configuration file uses generic transliteration. HPE recommends that you use generic transliteration because it is the best way to ensure that cross-lingual search can happen.

To enable transliteration for all languages

- In the `[LanguageTypes]` configuration section, set the `GenericTransliteration` parameter to `True`.

Generic transliteration performs transliteration as described in the following table.

Language or character type | Transliteration
--- | ---
Symbols | All dashes and hyphens to a hyphen character.
Latin | Accented characters to non-accented characters
Spanish | Accented vowels áéíóúü to non-accented vowels
Portuguese | Accented vowels àáâãçéêíòóôõúü to non-accented vowels
Greek | Accented Greek characters to non-accented characters
Cyrillic (including Serbian extensions) | All characters mapped to A–Z
Arabic | Arabic character normalization
Japanese | Half width katakana to full width katakana Full width 0–9, A–Z, a–z to single byte 0–9, A–Z, a–z
Chinese | Full width 0–9, A–Z, a–z to single byte 0–9, A–Z, a–z

For all other languages, transliteration does not apply, except for hyphen normalization.

Note: Languages with a sentence-breaking library might be transliterated as part of the sentence-breaking process.

When you set `GenericTransliteration` to `True`, it applies to all languages, unless you specifically disable transliteration for a language.

You can disable transliteration for an individual language by setting the `Transliteration` parameter to `False` in the individual language configuration section. This option completely disables transliteration for that language.
