This is absolutely right. In fact I am going to propose adding
strcmp(lower, "latin1") to the following test in
PyUnicode_AsEncodedString():
else if ((strcmp(lower, "latin-1") == 0) ||
(strcmp(lower, "iso-8859-1") == 0))
return PyUnicode_EncodeLatin1(...
I'll open a separate issue for that. In Python's own stdlib and tests
"latin1" is a more common spelling than "latin-1", so it makes sense
to optimize it.
