Just thought that we could go without `escape` and regular expressions just by using `indexOf` and its second argument.

````javascript
function find(text, token)
{
    var letters = token.split("");
    var matchIndex = 0;

    for (var i = 0; i < letters.length && matchIndex !== -1; i++)
        matchIndex = text.indexOf(letters[i], matchIndex);
    
    return letters.length !== 0 && matchIndex !== -1;
}
````
