escape_key(key) private

Memcache keys are binaries. So we need to force their encoding to binary before applying the regular expression to ensure we are escaping all characters properly.

        def escape_key(key)
          key = key.to_s.dup
          key = key.force_encoding("BINARY") if key.encoding_aware?
          key = key.gsub(ESCAPE_KEY_CHARS){ |match| "%#{match.getbyte(0).to_s(16).upcase}" }
          key = "#{key[0, 213]}:md5:#{Digest::MD5.hexdigest(key)}" if key.size > 250
          key
