Empty messages on some unusual utf8

[hilesaz]

In InputTextWidget::keyPressEvent a message that starts with U+FFFC will be passed through toPlaintext normally (so not get culled) but will end up as an empty

when passed through toHtml.

Looks like QTextEdit treats U+FFFC as a special character and there is no way to escape it.

Anyway, there are many special and noncharacter characters in utf8, so it makes sense to sanitize user input.

Which spacial characters do you mean? That one listed here?

Well, U+FFFC is used internally by QTextEdit engine and there seem to be no workaround for that.

Like the object replacement character U+FFFC and noncharacters from the Arabic block (U+FDD0 - U+FDEF), though I'm sure there are still many others.

Can't read Deutsch, but yes, some of them.

oops :D

I think the most simple fix would be to replace all "U+FFFC" inside the event with an empty string. I already have a patch for this but sending a PR will end in a (small) merge conflict with #120.
