Ugly coding, sorry...
Try this instead (works on ruby 1.9):
def encode(string)
map = {"symbol" => "spec_char" …. } # full it
start_index = 0
while match = string.match(/[\W]/, start_index)
new_char = map[match.to_s]
string[match.begin(0)..match.end(0)-1] = new_char
start_index = match.begin(0) + new_char.size # correct start_index
end
string
end
