The problem is that ctypes c_char (and c_char_p) creates unicode string
instead of byte string. I attached a proposition (patch) to change this
behaviour (use bytes for c_char).
So in next example, it will display 'bytes' and not 'str':
from ctypes import c_buffer, c_char
buf = c_buffer("abcdef")
print (type(buf[0]))
Other behaviour changes:
- repr(c_char) adds a "b"
eg. repr(c_char('x')) is "c_char(b'x')" instead of "c_char('x')"
- bytes is mutable whereas str is not:
this may break some modules based on ctypes
