Re: Encoding API exceptions

I'd be willing to experiment with changing the exception types in Chromium.
History tells us this sort of change is usually web-compatible, and the
feature still has pretty low usage numbers at this point.

It'd be nice to have more confidence about starting to use RangeError in
web platform features; IIRC an early iteration of the Encoding API design
did use RangeError but we moved away from it! Is there a new spec/feature
that can test the waters first?
