Hello everyone,

I am currently making a calculator and I want to insert the square root symbol as text for a button that will calculate the square root, but I don't know how to do that. I know that using an image is possible, but can we do it without an image?

Thank you very much.

Configuration: Windows 7 / Chrome 24.0.1312.52

    I don't know C# but I think you can use Unicode like in Java. 
    char radic = '\u221a';
    HTML special characters:    √    →    √    √

    Trust does not exclude control.

      The ASCII code indicates for the char variable 251, with good research
      Microsoft provides good answers, good luck since qbasic!
