struct Char


A Char represents a Unicode code point. It occupies 32 bits.

It is created by enclosing an UTF-8 character in single quotes.


You can use a backslash to denote some characters:

'\'' # single quote
'\\' # backslash
'\e' # escape
'\f' # form feed
'\n' # newline
'\r' # carriage return
'\t' # tab
'\v' # vertical tab

You can use a backslash followed by an u and four hexadecimal characters to denote a unicode codepoint written:

'\u0041' # == 'A'

Or you can use curly braces and specify up to four hexadecimal numbers:

'\u{41}' # == 'A'

See Char literals in the language reference.
