LYR-LEX0008

a character literal that holds no character or several

error · spec 01-lexical

Between the quotes of a character literal stand no characters ('') or more than one ('ab'). An escape counts as one.

Explanation

A character literal is one character, a Unicode scalar value: 'a', '\n', '😀'. Text of any other length is a string.

Write one character, or write the text as a string in double quotes.
