* Observations from Debug of 父娘<EFBFBD>:
* - The executable shows product name as 2RM - Adventure Engine
* - 2 calls to GetGlyphOutlineA with incompleted game
* - Memory location of the text is fixed
* - The LAST place accessing the text is hooked
* - The actual text has pattern like this {surface,ruby} and hence not hooked
*
* /HBN-20*0@54925:oyakoai.exe
* - addr: 346405 = 0x54925
* - length_offset: 1
* - module: 3918223605
