Additional sanity checking

I don't yet know what situation specifically triggered Simon's crash, because I
need more detail.

In the crash I stumbled upon, we were getting some seriously bogus values for
renderText->textLength(). However, under those same conditions,
renderText->caretMaxOffset() was 0. Checking that value before calling
convertUniCharToUTF8 with the bogus length solves my crasher.

Xan, thoughts?
