* 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).
* This can be modified. Textractor uses the modified sentence for future processing and display. If empty (starts with null terminator), Textractor will destroy it.
* Textractor will display the sentence after all extensions have had a chance to process and/or modify it.
* The buffer is allocated using HeapAlloc(). If you want to make it larger, please use HeapReAlloc().
* Param miscInfo: pointer to array containing misc info about the sentence. End of array is marked with name being nullptr.
* Return value: the buffer used for the sentence. Remember to return a new pointer if HeapReAlloc() gave you one.
* THIS FUNCTION MAY BE RUN SEVERAL TIMES CONCURRENTLY: PLEASE ENSURE THAT IT IS THREAD SAFE!
