There’s a solution. Use unicode emoji, and wrap them with backticks `.
In the table of contents, the title will be stripped of backticks, but keep the unicode emoj.
### Test 1
### `📣` Test 2
### Test 3
The drawback is that it looks odd in the post:
If you want the visually perfect solution but slighly convoluted:
### Test 1
### <span data-title-emoji>`🧑💻`</span> Test 2
### Test 3
With this CSS
span[data-title-emoji] code {
background: inherit;
}
Renders:
[wrap] won’t work for this purpose in a title, you must go with <span>
