Compilation issue of ASCII characters

[galloj]

Characters from line 42 and up aren't working.

The issue is following: short.c:42:1: warning: multi-character character constant [-Wmultichar]

It probably means that the compiler is trying to store those characters as UTF instead of ASCII. I guess it isn't probably that big problem as the language doesn't mention them in readme, but some of them are surely nice to have. I will maybe try to make PR later to fix it.
