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

[Bee]

Here it is:

$ xxd < test.swift

0000000: 7072 696e 7428 2248 656c 6c6f 2057 6f72  print("Hello Wor
0000010: 6c64 2066 726f 6d20 5377 6966 7421 20ed  ld from Swift! .
0000020: a0bd edb8 8020 2229                      ..... ")

I've asked Koding dev and they said their editor also has problem handling
unicode. They believe the problem is with the editor, not swift. 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.

Thank you.
