Because I implemented MS-Office files manipulation in my browser-side XForms implementation, such TextDecoder and TextEncoder are very interesting.

So TextDecoder is bytes to string and TextEncoder is string to bytes.
If we always represent the base64-variant as a sequence of bytes the
signature seems fine. If you want to get a string out of those bytes
again you could utf-8 decode it for instance.

I'd be interested in knowing what the level of interest is outside of
Google for this feature.
