Fix problem with PrettyFormatter printing URL encoded strings

[skloessel]

• Added a test case (should_print_encoded_characters) that prints URL encoded characters to the scenario in the form of a table .
• Adjusting of PrettyFormater .. instead of using String.format(..) - just appending
  1. the scenario indentation
  2. the line to be printed
  3. systems line-separator
     .. to the StringBuilder.

Fixes issues 2544
