Excuse my ignorance… Obviously something has changed but to my untrained eye, the git diff seems to show the same set of characters before and after. I'd love to learn what's happening if you can explain :)

@zpao second character in the first change and first character in the second change is different, if you look closely you'll see there's no horizontal line in between the two vertical lines in the new version.

'재' vs '제'

Not sure what either means, or what's right, but yeah 😄

Ah, I definitely missed that. Good catch :)
