Results of an item in account search that show the item in a shop or gallery do not show any unicode/emoji that is used in the gallery/shop name. Instead they are replaced by ?s.
Screenshot:

Unicode/emoji do not appear to work in forum posts or shop purchase notifications either (I tried to copy and paste the actual gallery name from above but it ended up as ?s as well. so below is the screenshot of what the name should be)

Hi - it doesn't look like this something that can fixed at this time (possibly with later updates).
For now, I'd recommend changing the name to not include the unicode if it does not work properly. Sorry!
Just an update since this board is still open: As stated on the other board about Emoji not working, "Emoji are only officially supported here via the emoji shortcodes. Unicode is not guaranteed to be supported at the moment, unfortunately."
