The problem is actually wider:: >>> getattr(None, "\udc80") Segmentation fault An idea would be to change _PyUnicode_AsDefaultEncodedString and allow unpaired surrogates (utf8+surrogateescape, as explained in PEP383), but I fear the consequences... The code that fails seems pretty common: PyErr_Format(PyExc_AttributeError, "'%.50s' object has no attribute '%.400s'", tp->tp_name, _PyUnicode_AsString(name)); It would be unfortunate to replace all usages of _PyUnicode_AsString to check the return value. Martin, what do you think?

The code that fails seems pretty common:
	PyErr_Format(PyExc_AttributeError,
		 "'%.50s' object has no attribute '%.400s'",
		 tp->tp_name, _PyUnicode_AsString(name));
It would be unfortunate to replace all usages of _PyUnicode_AsString to
check the return value.
