Unicode escape sequence not working

[KieranP]

I am trying to clear the console screen using an escape sequence:

      print("\u001b[H\u001b[2J");
      print("\u{001b}[H\u{001b}[2J");
      print("\033[0;0H\033[2J");

The above work in dozens of other languages, but none of them seem to work in Navi yet.

Does Navi have support for this sort of thing? And if not, what are the viable alternatives?

Thanks.

\u not yet supported.

Any suggestions in the meantime? I tried using try! process.exec("clear"); but it throws an error:

thread 'main' has overflowed its stack
fatal runtime error: stack overflow

I can't find a trace flag or anything for navi run that would provide more info about why it is occuring.
