UFT characters unsupported when pasted

[humdinger]

This is hrev46528.

When you paste a UTF character into a text field on page in Web+, you'll get only some control characters, like: ⊞a

Pulkomandy IRC: [19:22] <PulkoMandy> I think most of WebKit assumes the default encoding to be iso-8859-1 where it should be utf-8

[Still not sure about the category for this. Put it in Web+ for now.]
