See sharp with c#

[DaanVanMullem]

Klein foutje bij de String oefeningen: csharp/chapters/02/notebooks/solutions.ipynb
Nummer 6 waar toUpper & toLower moet gebruikt worden is 1 van de outputs:
Console.WriteLine(ReverseCase("h€11O W0rLd")); // Output: H€11o w0RlD

De werkelijke output is: H?11o w0RlD aangezien de char.toUpper(€) = "?"

This issue appears to be client-specific. In the latest version of the notebook, the problem cannot be reproduced. However, when running the code in a terminal, the issue occurs. The root cause is the Console.OutputEncoding. By adding Console.OutputEncoding = System.Text.Encoding.UTF8; to the application, the issue is resolved. The problem stems from certain console encodings that cannot display the character properly, causing it to fall back to ? as a placeholder.

This issue can be closed now @vertonghenb.
