# Starting in python 3.6.3 it is no longer possible to use:
# LPCWSTR(path + '\0') directly as embedded null characters are no longer
# allowed in strings
# Workaround
# - create buffer of c_wchar[] (LPCWSTR is based on this type)
# - buffer is two c_wchar characters longer (double null terminator)
# - cast the address of the buffer to a LPCWSTR
# NOTE: based on how python allocates memory for these types they should
# always be zero, if this is ever not true we can go back to explicitly
# setting the last two characters to null using buffer[index] = '\0'.
# Additional note on another issue here, unicode_buffer expects length in
# bytes essentially, so having multi-byte characters causes issues if just
# passing pythons string length. Instead of dealing with this difference we
# just create a buffer then a new one with an extra null. Since the non-length
# specified version apparently stops after the first null, join with a space first.
