RegEx stuff

a = [["a^b^^"], ["c&def"]]
b= []

a.to_s.each_byte { |byte| (b.push(byte.chr) if !b.include?(byte.chr)) if
byte.chr.match(/\W+/) }

b.each do |c|
a=a.to_s.gsub(c, "\\#{c}").to_a
end

p a

=> ["a\\^b\\^\\^c&def"]

How come the & does not get subbed with '\\&' ??

I'm basically trying to substitute any special character with
'\\#{special_character}'

THANKS!

try
a=a.to_s.gsub(c, "\\\\#{c}").to_a

"\\" will present as '\'
'\&' will present as '&'
