You can ask it to spell out words, which it will do. I asked it to do this and it was successful. I then intentionally misspelled a word (e-i transposition), and it gave me the correct spelling. I asked it if that was how I spelled it, and it confirmed that it wasn't but that the way I had spelled it was incorrect (and noted the e-i transposition).

So while it may may receive input as word tokens, I'm not sure that that means it can't "see that at all".

I will note that I don't have a good understanding of chatgpt at all.
