Subject: invalid byte sequence in US-ASCII (ArgumentError)

I'm having some trouble migrating from 1.8 to 1.9.1. I have this line of
code:

text.gsub! "\C-m", ''

...which generates this error:

/home/luther/bin/dos2gnu:16:in `gsub!': invalid byte sequence in
US-ASCII (ArgumentError)

The purpose is to strip out any ^M characters from the string. I've
tried a couple of different magic comments with utf-8, but the error
message still shows the same "US-ASCII". I also tried changing the \C-m
to 13.chr, but I still got the same error, suggesting that control
characters aren't even allowed in strings anymore.

I'm sure this must be a common migration problem, but I can't find a
solution no matter how hard I search the web. Any help would be greatly
appreciated.
