If I understand you correctly you can leverage Ruby's parser to
interpret your string literal:

irb> x = '\u041f\u0440\u0438\u0432\u0435\u0442!'
=> "\\u041f\\u0440\\u0438\\u0432\\u0435\\u0442!"
irb> eval("\"#{x}\"")
=> "Привет!"

Be careful though with eval, make sure your string to be evaluated doesn't contain any untrusted code.
