Hi guys When I sign up through the datahub invitation link, if I write the full name in Korean, it comes out as ???. how can i fix it ??

Hi there! this is actually a known issue with supporting character-based languages for certain things (like your username). This is something we're looking into and will hopefully have an update for you soon!

If you change to english characters it works?

@big-carpet-38439 yes, changing it to english works fine.
