Overview
A Char
represents a Unicode code point.
It occupies 32 bits.
It is created by enclosing an UTF-8 character in single quotes.
'a'
'z'
'0'
'_'
'あ'
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.
