Steps to reproduce the problem:
The W3C I18N WG in concert with WHATWG is testing Encoding specification support. For the encoding Shift-JIS, our tests produce 30 errors in Chrome. 

See: https://github.com/whatwg/encoding/issues/61

What is the expected behavior?
No errors detected.

What went wrong?
See encoding bug above. Please respond to that issue in whatwg's github.

Did this work before? No 

Chrome version:   Channel: n/a
OS Version: 
Flash Version: Shockwave Flash 22.0 r0

Note: this may be an error in the specification or an error in the tests, in which case we'd very much like to know!
