[swift-users] emoji in source code failed to compile in linux ubuntu

[Alex Blewitt]

If you run the XXD command it will print out the hex values, which is the important thing (as opposed to a screenshot which doesn’t have that information). For example, it might be using UTF-16 or some other variation.

Can you open Terminal and run 

xxd < test.swift

and then copy/paste the text into a mail response? Then we can figure out what’s wrong.

Thanks,

Alex
