Plain old text that can be selected is always going to be the most user friendly to non-native speaker users.

The question then is on the balance of trade offs which user group experience is the one you want to cater more to, non native speakers or keyboard-only users.

Edit: I love how one of the icons is 票 - perfectly self explanatory to Chinese speakers. Good luck if you don't speak Chinese which goes to show that icons are cultural to some degree
