Strip high bit from text?

[David Kelly]

I regularly get email from a Blackberry user which my ISP then adds
this header, "X-MIME-Autoconverted: from quoted-printable to 8bit". So
far so good but the result always contains a number of 0xa0's in places
a plain old space belongs. Mutt/vim renders these as "?" making a
complete mess of things.

Already use procmail so adding an automatic filter should not be
difficult if only I can come up with on.

Tried "tr \240 ' ' < testfile | hd" and was not able to change the 0xa0
into anything. Have already spent much more time trying to make tr or
sed do the job than it would have taken to knock something out in C, but
I think there should be something laying around already in the base
system to perform this task.

Suggestions? Repair the email while procmail has it? Reconfigure mutt
and/or vim?
