I don't see why do you think this would present a problem. The conversion of 
the first string will end in an unpaired high surrogate. The conversion of 
the second string will start with an unpaired low surrogate. The two, when 
concatenated, will form a valid UTF-16 encoding of a non-BMP character. 
Where is the issue here?
