Characters

A value of type Char, also known as a character, is a Unicode scalar value. It is represented using an unsigned 32-bit integer and is statically guaranteed to be a valid Unicode scalar value.

Syntactically, character literals are enclosed in single quotes.

#eval 'a' -- 'a'
#eval '∀' -- '∀'

Characters are ordered and can be decidably compared using the relational operators =, <, ≤, >, ≥.
