Our service has detected that German is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that Tango-bs.de main page’s claimed encoding is iso-8859-1. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
