A unicode constant can be handy but can ONLY be defined as a local constant and not globally 
see <https://xojo.com/issue/56192>
and <https://xojo.com/issue/55502> (i wrote a long blog post about how to work around this limitation)
The solution is likely to write some code to put the desired string on the clipboard, and then paste it into the constant definition the IDE…I have been doing that for years for things I could not type in.

I’ve done that as well it just makes it very inobvious that there IS anything there since they are not visible
