We've recently noticed a lot of users inquiring about not being able to use emojis while messaging other users.
Unfortunately, Wattpad is currently unable to support most emojis on our platform (in writing, commenting, and private messaging). We've seen that sometimes a few very basic emojis will work, but we are yet to build the capability to read all emojis on Wattpad.
A lot of our users have asked for this ability though, so we hope to develop this in the future.
Thanks you for your understanding!
