Selecting The Language To Use
1. Setting the Language / Locale
The locale describes the regional settings for a piece of software, such as a website, or unblu. The most noticeable aspect of the locale is the language in which the user interface is displayed, but the locale can contain other regional aspects (such as date formats, number formats, and so on).
If your website has only one locale, you can set that locale for unblu in the configuration. This makes sure that the website and unblu use the same locale (that is, the same language and the same other regional settings).
If your website supports multiple locales, then you have to tell unblu which locale to use.
2. Using an attribute
A very straightforward way of telling unblu which locale to use is by using the default html
lang attribute in the
<html> tag, as follows:
IMPORTANT: Although according to the html specification, the
lang attribute can be set on any tag, unblu only checks the html tag to pick up the language.
unblu supports either language code or language-region code as defined in http://www.ietf.org/rfc/bcp/bcp47.txt section 2.2.1(language), section 2.2.4 (region) and Appendix A (Examples for language-region). For more information, see http://www.w3.org/International/tutorials/new-language-decl/qa-html-language-declarations. If you do not want to set the language for the entire page, you can tell unblu explicitly what locale to use. To do so, add the (custom) attribute
unblu_locale to the html tag as follows:
Most content management systems will let you add this attribute to all pages with little effort.
Note that you have to call the function after the unblu snippet, but before the page is rendered. If at all possible, we recommend to place the call immediately after the snippet.
4. Languages and regions
The language code follows the IETF convention for language codes, so the following calls set the locales for English, US-English, and German as spoken in Germany:
