There are two basic types of literals: strings and numbers. A string is just a run of printable ASCII, and a number is just a run of the superscript digits ?123??????.
Examples:
foo is equivalent to "foo".
foo?bar is the same as "foo\nbar".
123? is 1234.
In a Charcoal program, expressions are implicitly printed. Numbers print a line, and arrows can be used to specify a direction.
Examples:
foo prints foo
foo? prints foo----
foo↖? prints:
\

\
foo\
