Py_UCS4 is indeed what we're talking about here. What I don't understand is why you raise a compile error; AFAIK, unsigned long is at least 32 bits on all platforms and that's what the Unicode implementation would need to support UCS4 -- more bits don't do any harm since the storage type is fixed at 16-bit UTF-16 values. Ideal would be combining the above with the C9X typedefs, e.g. typedef uint4_t Py_UCS4; -- Marc-Andre Lemburg ______________________________________________________________________ Business: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
