[R] How to remove non-UTF-8 characters from a string

[Bos, Roger]

All,

I am trying to post text from an XLS spread to my wiki and I need to
remove any characters that are not UTF-8.  Is there an easy gsub command
that can do this?

(I previously sent this same email to r-sig-gui.  That was a mistake and
I apologize for the duplication.)

Thanks, Roger J. Bos
