Answer 1

Your string is in escaped unicode format. If it is always in this format you can simply strip out the escaping U characters and convert the hex to code points.

  var original = 'u9c9cu82b1u548cu7231';

  // split on 'u' and remove the first empty element
  var parts = original.split('u')..removeAt(0);

  // map from hex string to code point int, and create string
  print(String.fromCharCodes(
    parts.map<int>((hex) => int.parse(hex, radix: 16)),
  ));
