Would the emojis be displayed ok?
I tested and checked modern internet browsers like Chrome, for you to check if the emojis are displayed properly on mobile and desktop.
I wondered, should I you use emojis in WordPress menus, posts and pages?
It used to have the disadvantage that not all browsers handled emoji incorrectly. This happened in cases where the server could not change the coding of the WordPress database for various reasons. It would then convert the emoji codes to HTML equivalents, which unfortunately showed up as a string of strange characters.
As of today, everything works. I have checked on all popular browsers that the emoticons work. I even fired up my old Samsung Note 3 phone and its built-in browser. The multilingus.com website correctly displayed the emoji in the menu.
Yes, on this site I used the usual emoji typed directly from the osx (or Apple Mac) system I work on. Everything looks ok, for checking I inserted some emoticons below ? :
