How can I use a character code to add a character to text?
You need to insert it as an HTML entity . If possible it's probably clearer to use a character's entity name- in this case that's ←, or it might be something like © or >- but for an arbitrary char code you can surround it with the & and ; that indicate an entity, then ahead of the number put # (to indicate it's a number) and x (specifically to indicate it's a hexadecimal)- so ← is what you'd use in this case. ETA: If you need to handle larger amounts of text that may have a combination of simple ASCII characters and more complex ones, you should use the library he to encode/decode. More on reddit.com

It also occurs to me well after the fact that the reason String.fromCharCode isn't working for you is that the code 2190 is a hexadecimal, but you have to indicate it's a hex literal when you pass it.
