Since Plesk is a web application, a single instance may simultaneously target an international, multi-language audience owing to the possibility of localization. Localization means a process of adapting software for a particular country or region, which is, generally speaking, translating Plesk user's environment to a language spoken in the country or region.
A subset of Plesk user's environment adjusted to a particular language and culture is called locale. The Locale Components section answers what substitutes a Plesk locale.
On the implementation level, a particular locale is represented by the corresponding language pack (LP). Language pack is an installable file containing all the resource files and processing instructions necessary for installing a particular locale to an existing Plesk instance. In other words, LP is a packed set of files containing all the language-related data that define the appearance of a particular user environment component. The Language Pack Content section focuses on what files are included to an LP, how the files must be structured, and shows how these files are related to locale components.
Plesk locale and language pack names follow the RFC 1766 standard in the format "<languagecode2>-<country/regioncode2>", where <languagecode2> is a lower-case two-letter code derived from ISO 639-1 and <country/regioncode2> is an upper-case two-letter code derived from ISO 3166. For example, U.S. English locale is named "en-US". To see a list of locale names supported by Plesk, refer to the Appendix Locale Codes.
Note: This 4-letters format of Plesk locale and LP names is supported since Plesk 8.2. For information on previous Plesk versions, please visit the Parallels forum devoted to localization discussions: http://forum.swsoft.com/forumdisplay.php?s=dfb0a55333e42b791a9f11a560caf701&forumid=207.
Plesk supports an arbitrary number of locales (depends on the purchased license). A particular locale can be represented by only one LP, that is, you cannot install, for example, two different en-US language packs.
By default, Parallels Plesk Panel is shipped with only U.S. English language pack. Parallels also releases LPs for 9 additional languages, which are:
These language packs are available for downloading at the Parallels Web Site.
This Plesk Localization Kit is designed to allow third-party developers to create their own localizations for Plesk.
Note: To install and use additional LPs, be sure to have a Parallels Plesk Panel license key which allows multi-language support with a required number of language packs.
