Check out the Regexp documentation, specifically the '= new'/'compile' method:=C2=A0http://www.ruby-doc.org/core-1.9.3/Reg= exp.html#method-c-new. I think you'll need to use Regexp.compile to= create an "encoding-less" regular expression.

I would guess something like this -

[3,4,5,6,7].each do |n|
=C2=A0 =C2=A0 l= ine.gsub!(Regexp.compile('\377\37' + n.to_s + '\001', nil, = 'n'),"")
end
<= /div>

You'll have to fiddle with it, as I didn't have a cha= nce to test it out to see if this actually works. I'd have to know the = encoding the 'line' variable to accurately test it anyway.

Here's the code:

[3,4,5,6,7].each do |n|
=C2=A0 =C2=A0 line.gsub!(/#{('\377\37' + n.to_s + '\001')}/= ,"")
end

Many thanks in advance!
