+Subject: [PATCH] Convert unicode index to long, not int, in get_char_index
+
+There's an error in the `PyFT2Font.get_char_index()` method
+added in 2d56ffeb . The type for the unicode index to be sent
+to `FT_Get_Char_Index` is `FT_ULong` - an unsigned long - but
+the `PyArg_ParseTuple` call that converts it from Python used
+`I` in the format string, which converts a Python int to a C
+unsigned int, not a C unsigned long. This doesn't seem to cause
+a problem on little-endian arches, but it results in completely
+incorrect conversion on big-endian arches, which in turn would
+result in wrong glyphs, unfound glyphs, and even in an infinite
+recursion in `UnicodeFonts._get_glyph`.
+
+To get correct conversion we must use `k` not `I`, which is
+the specifier for a C unsigned long.
