Thanks, that sounds like a great solution if Arni doesn't want his own

For one thing, the tools package is intended to be tools used by R, not by users. R doesn't need this function, so it doesn't belong in tools. (Some other functions in tools like showNonASCII have come to be used by users, but their primary purpose is for R.)

So I'd suggest that you add this function to some package that you maintain (perhaps a new one, containing a collection of related utility functions), or search CRAN for an appropriate package with a maintainer who is willing to take this on.
