Check calls of PyUnicode_AsEncodedString() for NULL return, probably because the encoding name is not known. Add special treatment for SQL_ASCII, which Python definitely does not know. Since using SQL_ASCII produces errors in the regression tests when non-ASCII characters are involved, we have to put back various regression test result variants.
