/** Artikash 8/10/2018: Ren'py
*
* Sample games: https://vndb.org/v19843 https://vndb.org/v12038 and many more OELVNs
*
* Uses CPython, and links to python27.dll. PyUicodeUCS2_Format is the function used to process text.
* first argument. offset 0x18 from that is a wchar_t* to the actual string
* ebx seems to work well as the split param, not sure why
