To make text strikethrough using unicode, I have been using this:

function strikeThrough(text) {
  return text
    .split('')
    .map(char => char + '\u0336')
    .join('')
}

My question is: is there a similar way to do this for Bold and Italic as well, by adding a unicode character in the same manner? I'm trying to avoid an html-based solution. For example:

function boldText(text) {
  return text
    .split('')
    .map(char => char + '????')
    .join('')
}

function italicText(text) {
  return text
    .split('')
    .map(char => char + '????')
    .join('')
}
