Meta Content-Language

The tag allows you to specify the primary language for the entire document. Widely used by browsers, search engines, reading systems aloud, text analysis systems and automatic translation. Important for the correct choice of algorithms for automatic detection of encodings for any language, including English. A common mistake when creating a new page from a template where by default one language (most often English) is installed, the choice of the encoding for another can be set to lead to a low ranking in search engines, to false triggers of automatic translation systems, built into modern browsers and many other minor inconveniences . The most significant becomes when using Unicode encodings, in particular the most used UTF-8

< meta http-equiv = "content-language" content = "de" />

In HTML5, the language is simplified:

< html lang = "de" >
