This character is, I believe, the "non-breaking space". It's often
used in rendering code which might otherwise not be properly formatted
in a web browser, but it ruins the code for copy-and-paste.

You've got the exact right idea. I hesitate to post this one-liner,
because there's nothing really wrong with the program you posted. But
I use something like this for similar fixups:
perl -pi.bak -e 'tr/\xA0/ /' filenames*
Perl has a number of command-line options that are useful for simple
file transformations, so that's how the -p and -i.bak replaced most of
your code. (perlrun manpage.)
The tr/// (perlop) is the transliteration operator, and it should be
*slightly* more efficient at this kind of operation. (I say, it should
be, but there's no substitute for benchmarking, and your data may
vary. And, slightly.) But that's how I'd write it.
Cheers!
