Fix UTF-8 in the surrogate range passing as good.

Browse source 
Our UTF-8 validity checker failed to recognize that characters in the surrogate range (D800-DFFF) were invalid. Fortunately, Python 2 is happy about that, therefore it doesn't crash (Python 3 fixed that range too). Unfortunately, SL isn't, therefore we fix it.

Added corresponding unit tests.
