Well, I don't particularly have that problem because I don't
have a huge number of scripts and for the ones I do it would be
relatively simple to do a scan and update - or just run them
with the unit tests and see if they break!
In fact, I think that a scan and update program in the tools
directory might be a very good idea - just walk through a
Python library, scan and update everything that doesn't
have a declaration.
The issue has popped in and out of my awareness a few
times, what brought it up this time was Hallvard's thread.
My specific question there was how the code handles the
combination of UTF-8 as the encoding and a non-ascii
character in an 8-bit string literal. Is this an error? The
PEP does not say so. If it isn't, what encoding will
it use to translate from unicode back to an 8-bit
Another project for people who care about this
subject: tools. Of the half zillion editors, pretty printers
and so forth out there, how many check for the encoding
line and do the right thing with it? Which ones need to
