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

[Alex Blewitt]

Yes, I think there is a problem in the way that the Unicode is being entered. The unicode sequence for UTF-8 should look like f0 9f 98 83 0a.

However it looks like the character is being encoded in your file as: ed a0 bd ed b8 80 which I’m not sure where that’s come from. But it does look like the editor that you’re using isn’t converting the unicode to the right value.

In the meantime, you can print out a smiley by entering a unicode escape sequence as follows:

print("Hello \u{1f603}")

They suggest to prevent using unicode directly inside the code, and use the unicode code instead. So, I think the problem has been cleared, although the ideal solution is currently being worked on.
