Bug/ios emojis

[brunolm]

Fixes #98

Replaced split('') with a for of loop so it doesn't break iOS emoji's on webview.

Some emotes are 2 characters in length, so in a for (const char of chars) char.length will be 2 for most emotes, for a few others they will be followed by a char (code = 65039)

for of + handle 65039 vs old split('').map()

console.clear();
var str = 'a😂 ☺️ ☠️ 😭a';

var chars = [];
for (const char of str) {
  if (char.charCodeAt(0) === 65039) {
    chars[chars.length - 1] += char;
  }
  else {
    chars.push(char);
  }
}

console.log('for of');
console.log(chars);

console.log('array map');
console.log(str.split('').map(x => x));

Breaking tests

I don't know why the docker tests are not working, but the PR is here in case you want to work on this feature.

Thank you for the detailed PR description. I’ve added support for emojis in the latest release.

I ended up using the array spread operator to split the string which handles emojis correctly.
