HTML files are detected as utf-16 when meta content is set to "unicode".
Shouldn't the default be utf-8?
The attached sample file is shown correctly in:
Chromium Version 55.0.2883.75
I am aware that there is no charset "unicode" (available character encodings: http://www.iana.org/assignments/character-sets/character-sets.xhtml)
Unfortunately there are many wrong encodings used out there.
All unknown encodings should be validated or at least be set to default utf-8.
