10.1.2.3 Characters
The full 8-bit ASCII code set can be used in source files. Characters not in
the character set defined in the standard are permitted only within character
constants, string literals, and comments. The -h [no]calchars option allows
the use of the @ sign and $ sign in identifier names. For more information on the
-h [no]calchars option, see Section 2.7.3, page 15.
A character consists of 8 bits. Up to 8 characters can be packed into a 64-bit
word. A plain char type, one that is declared without a signed or unsigned
keyword, is treated as an unsigned type.
Character constants and string literals can contain any characters defined in the
8-bit ASCII code set. The characters are represented in their full 8-bit form. A
