Fails to build on windows outside of cygwin or msys/mingw64

[xrheihwh]

Two different errors I encountered. The first one is that I get the following terminal output:

Traceback (most recent call last):
  File "D:\Users\Matthew\downloads\thebookofshaders\src\parseBook.py", line 73, in <module>
    fileString = originalChapter.read()
                 ^^^^^^^^^^^^^^^^^^^^^^
  File "D:\msys64\mingw64\lib\python3.11\encodings\cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 4870: character maps to <undefined>
make: *** [Makefile:17: pdf] Error 1

I fixed this by setting encoding='utf-8' in the open functions.

My second issue is something I cannot figure out why because it works with mingw64 shell.

  File "D:\Users\Matthew\downloads\thebookofshaders\src\parseBook.py", line 78, in <module>

I don't know if windows was ever intended for being built on, but just wanted to file a bug report it fails to build on windows outside of some sort of POSIX emulation.
