Issues with decodeURIComponent and UTF-8 Characters

When using DataView#getString `decodeURIComponent` will fail with **URI Error: URI Malformed** when first escaping a sequence like "\251art" (Leading Copyright sign, this is the field name of MP4 Metadata for Artist) and then decoding it.

If you simply avoid escaping in the first place it will come out as expected showing the copyright sign.

Can you come up with an example of where this would fail? I could imagine when there are surrogate pairs encoded in UTF-8 it might be failing, but then again I have no test ready to show it.
