[New-bugs-announce] [issue2280] parser module chokes on unusual characters

[David Binger]

New submission from David Binger <davidbinger at mac.com>:

This is with the current revision of py3k: 61353.

parser.suite('"\u1234"') fails with a TypeError.

Changing the argument format from "s" to "s#" works around this problem.

I added a unit test for this.  After fixing the "s#", another
bug is exposed by the same test: a string literal containing
\u1234 is mangled by sequence2st().

The last section of the patch seems to correct the second bug.

(I think getarg.c's handling of "s" has a problem
handling a unicode string containing a character whose 
encoding is not 1 byte.  It has a test for null bytes
at the end that does not work correctly.)
