I wasn't sure whether the string object was still a string after
"encode" is called... at least whether it's still an ascii string.
And if not, whether it could be used w/ dumps.  I tested your
variation and it works the same.  I guess your "write" is doing the
same as my "dump", but may be more efficient.  Thanks.
