/**
* You shouldn't mess with this or even look at it unless you're certain you know what you're doing.
* Param sentence: pointer to sentence received by Textractor (UTF-16).
* You should not modify this sentence. If you want Textractor to receive a modified sentence, copy it into your own buffer and return that.
* Please allocate the buffer using HeapAlloc() and not new[] or malloc() or something else: Textractor uses HeapFree() to free it.
* Param miscInfo: pointer to start of singly linked list containing misc info about the sentence.
* Return value: pointer to sentence Textractor takes for future processing and display. If nullptr, Textractor will destroy the sentence.
* Return 'sentence' unless you created a new sentence/buffer as mentioned above.
* Textractor will display the sentence after all extensions have had a chance to process and/or modify it.
* THIS FUNCTION MAY BE RUN SEVERAL TIMES CONCURRENTLY: PLEASE ENSURE THAT IT IS THREAD SAFE!
