I would make the check more aggressive in that it complains about
anything not using normal printable characters (in the ASCII sense)
and add a second variable for the case where we need to overwrite it.
The hardest part is making sure that there are no regressions.

If you send me a patch that can includes this optionally and logs any
difference between the old approach and the new one, I can include it in
a bulk build.
