Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Telsol.de can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else) and no language is claimed in <html> or <meta> tags either.

Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.
