Unicode control caracters in parameters - java.lang.IllegalArgumentException: Illegal number of path parameters. Expected 1, was 2.

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
Parameters in get() method that have unicode control caracters fail with an 
IllegalArgumentException

Example:
                String request = "param1={param1Value}&param2={param2Value}";
        String param1Value =  "Hello";
        String param2Value =  "Hello\u0085";
        System.out.println(param1Value);
        RestAssured.get(request, param1Value, param2Value);

What is the expected output? What do you see instead?
Success of method call get()

What version of the product are you using? On what operating system?
2.4.1

Please provide any additional information below.

The error is in com.jayway.restassured.internal.RequestSpecificationImpl:
     def hasAnyTemplateLeft = ~/.*\{\w+\}.*/

This regex only takes words and not others caracters.

 if (queryParams.matches(pathTemplate)) {
        def hasAnyTemplateLeft = ~/.*\{\w+\}.*/
        def replacePattern = ~/\{\w+\}/
        def definedParams

..... else {
          throw new IllegalArgumentException("Illegal number of path parameters. Expected $numberOfUsedPathParameters, was $expectedNumberOfUsedPathParameters.")
        }
      }

I used another library as the performance of rest-assured was 50x to 100x 
slower than regular httpclient and json-simple.

Because of this issue I found that rest-assured is super slow for the kind of 
work I do. I execute concurrent tests that run for hours (> 200K requests), 
Rest-assured is very inefficient because of groovy code I suppose.
