Graph indicating that UTF-8 (light blue) exceeded other main encodings of text on the Web in December 2007, and that by 2010 it was nearing 50% (and up to 82% in January 2015). Encodings were detected by examining the text, not from the encoding tag in the header,[3] thus does not include ASCII tagged as UTF-8. As ASCII is valid UTF-8 it could be added to the UTF-8 to get over 65% usage.
