> Does anyone know what other compilers use signed chars? Most of them do, including gcc, on most platforms. unsigned char is really the uncommon case. The patch is incorrect; Py_CHARMASK is correct as it stands. It is not the objective of Py_CHARMASK to produce a char, but (as the comment above its definition explains) to produce an int. The question really is why you get a value of -1 into c in the first place. Could it be that you are past the end of file, and reading EOF "characters"?

The patch is incorrect; Py_CHARMASK is correct as it stands. It is *not* the objective of Py_CHARMASK to produce a char, but (as the comment above its definition explains) to produce an int.
The question really is why you get a value of -1 into c in the first place. Could it be that you are past the end of file, and reading EOF "characters"?
