To Reproduce Steps to reproduce the behavior:

1. Parse an expression with a NBSP character (<0xa0>)
2. Verify that the parsing failed

"The engine" should "evaluate expression wirth NBSP character" in {
    evaluateExpression("1 +   2") should returnResult(3)
  }

Expected behavior The engine can parse expressions with NBSP characters. It should be interpreted as whitespace.
