Javascript allow special characters in textarea (Electron App)

Question

I am making an Electron app that has a <textarea> .

I am using document.execCommand('insertText', false, text); to insert text into the text area.

I want to insert the following string 'ⓐ' however when I do this my text area displays the following: 'â“'.

How can I insert the special character with document.execCommand ?

Answer 1

you need to use code like this

var spchar = string.fromCharCode(???)
document.execCommand('insertText', false, spchar );

and add it to textarea

please check maybe your textarea use another font that shown your character wrong

Answer 2

Inside a textarea, you need to convert the following characters into their HTML entities. This is not a limit caused by electron.

You are not specifying the server side language you're using. In PHP, the correct function would be htmlspecialchars() .

As of your example, we can only tell that you're using javascript, so the JS-only solution would be to replace with the equivalent entity code:

function escapeHtml(text) {
  return text
      .replace(/ⓐ/g, "ⓐ")
      ...
}

You can find the symbol's equivalent entity code here: https://www.compart.com/en/unicode/U+24D0
