In any programming language that existed before this question was asked, write a program (not a function) that outputs the characters
Hello world! followed by a newline. Your program:
- should not use any character more than once (including whitespace)
- should only use ASCII characters
- should not use any built-in libraries
- should not get input (user, file, filename, system variable, internet, anything)
- should not output anything else
Winner is whoever has the most votes after 14 days and abides to the six rules.
The sixth rule is that you cannot use H9+, HQ9+, HQ9+B, HQ9++, HQ9+2D, Hello, Hello+, Hello++, Hexish, CHIQRSX9+, or Fugue. Also, all answers which require implementations that are newer than this challenge must be marked as non-competing.
Disclaimer: This question was posted with the assumption that Hello world! with limited repetition did not cause any damage to your computer or your brain in the process of coming up with the answers.
