Subject: Ruby 1.9.2: How to sanitize text with invalid characters?

I process a lot of text files of which I know the encoding, but that
might contain a few bytes that are invalid (i.e., make gsub fail with
"ArgumentError: invalid byte sequence in US-ASCII/UTF8"). What's the
best way to handle this situation gracefully, by ignoring or removing
the invalid characters?
