Language Id Format

Use this dialog to specify what kind of language ids are used when writing files.

Language id format

Specifies how to format language ids used in xml:lang attributes. Possible values are:

Value	Description
Standard: la[-Ssss][-CC]	Standard language id that contains an ISO 639-1 language id (la) and optional script id (Ssss) and/or ISO-3166 country id (CC).
Legacy: la[-CC]	Legacy language id that contains an ISO 639-1 language id (la) and an optional ISO-3166 country id (CC). If the id uses the secondary script of the language (e.g., Traditional Chinese), then the country id is required.
Underline: ll[_CC]	As above, but separator character is underline, "_", instead of the hyphen, "-".

It is recommended to use the default language ids (either Use the same format as in the original file or Standard). Use other formats only if your files are consumed by a system that requires legacy ids.

Language id case

Specifies the case of the language attributes that are used in the file. Possible values are:

Value	Description
Standard (la-CC)	The language part is written in lower case. The optional country part is written in the upper case. For example, en-US is for English in the United States. This is the default value.
Lower (la-cc)	Both language and country parts are written in lower case. For example en-us
Upper (LL-CC)	Both language and country parts are written in upper case. For example EN-US

Include script into ids

Specifies when the script part is included in the language id. This is visible when language id format is set to Standard. Possible values are:

Value	Description
Standard	Script id is included if it is absolutely needed to make id unambiguous. For example, English is `en`, Simplified Chinese is `zh`, and Traditional Chinese is `zh-Hant`.
On multiple scripts	Script id is included if the language can use more than one script. For example, English is `en`, Simplified Chinese is `zh-Hans`, and Traditional Chinese is `zh-Hant`.
Always	Script id is always included. For example, English is `en-Latn`, Simplified Chinese is `zh-Hans`, and Traditional Chinese is `zh-Hant`.

Include country into multi-script ids

Specifies when the script part is included in the language id. This is visible when language id format is set to Legacy or Underline. Possible values are:

Value	Description
No	A country id is not added if not implicational given. For example, English is `en`, Simplified Chinese is `zh`, and Traditional Chinese is `zh-TW`.
Yes	A country id is included if the language has more than one possible script. For example, English is `en`, Simplified Chinese is `zh-CN`, and Traditional Chinese is `zh-TW`.
