Fixed tests below should be added across all languages

• ""

• "%$&/#·@|º\ª"

• Description should be language-agnostic

• Should mention whether an empty or completely noisy string will be accepted

C# As prior to Kaiyou's issue below, it should use PascalCase (which is the one in the current initial solution setup)

When F# is selected, the description shows a code block for Ruby.

fix the typos in the function name

JS: Node v12 should be used enabled along with its appropiate assertion tools (Mocha + Chai).

assertSimilar is deprecated, use assertDeepEquals

Very nice, btw.

Citate from task description: "We know that our messages can't be written using %$&/#·@|º\ª and white characters (like spaces or tabs)."

But unit tests expects "hello world" phrase with space between words.

C#: Initial code has a method called RemoveNoise, but everywhere else in the kata removeNoise is expected.
