Removing VT220 control characters with GAWK

[Dylan VanHerpen]

I've been trying to use GAWK to remove VT220 control characters from an
Expect capture file. The pattern I'm trying to remove is as follows:

        ESC[xx;xxH

Where 'xx;xx' represents the row/column. What I'd like to do is
something like this:

        { FS = "\033\[*H"; OFS = "," }

So far, I've had no luck removing the escape strings, or even just the
escape code (\033) itself. Am I going the wrong way about this?
