I18N Tests: Character encoding detection

The following tests examine whether a user agent is able to detect a UTF-8 document served as US-ASCII and correctly display the text.

Even if a page is served as us-ascii, some browsers may recognize that the file is actually in a UTF-8 encoding and override the declared encoding.

1. C1 range codepoints   (results)
2. HTML5 charset attribute   (results)

4. UTF-8 auto-detection with static HTML file   (results)
5. UTF-8 auto-detection with object   (results)
