mPDF recognises IETF language tags as:
|
|
- a single primary language subtag composed of a two letter language code from ISO 639-1 (2002), or a three letter code from ISO 639-2 (1998), ISO 639-3 (2007) or ISO 639-5 (2008) (usually written in lower case);
|
|
- an optional script subtag, composed of a four letter script code from ISO 15924 (usually written in title case);
|
|
- an optional region subtag composed of a two letter country code from ISO 3166-1 alpha-2 (usually written in upper case), or a three digit code from UN M.49 for geographical regions;
|
|
Subtags are not case sensitive, but the specification recommends using the same case as in the Language Subtag Registry, where region subtags are uppercase, script subtags are titlecase and all other subtags are lowercase.
|
|
|
|
Region subtags are often deprecated by the registration of specific primary language subtags from ISO 639-3 which are now "preferred values". For example, "ar-DZ" is deprecated with the preferred value "arq" for Algerian Spoken Arabic;
|
|
|
|
Example: Serbian written in the Cyrillic (sr-Cyrl) or Latin (sr-Latn) script
|
|
|
|
und (for undetermined or undefined) is used in situations in which a script must be indicated but the language cannot be identified.
|
|
e.g. und-Cyrl is an undefined language written in Cyrillic script.
