G.3.4 Characters

There are no source and execution characters that are not explicitly specified by the

ISO/ANSI C Standard.

These are the escape sequence values produced for the listed sequences:

The HP NonStop operating system handles the shift states used for the encoding of

multi-byte characters; therefore, it is not applicable to list them here.

There are 8 bits in a character in the execution character set.

There is a one-to-one mapping of members of the source character sets (in character

and string literals) to members of the execution character set.

The value of an integer character constant, that contains a character or escape

sequence not represented in the basic execution character set or the extended

character set for a wide character constant, is -1.

When there is an integer character constant that contains more than one character or a

wide character constant that contains more than one multi-byte character, the compiler

concatenates the characters to form either a short or long integer, depending on the

length of the constant.

The C-locale is used to convert multi-byte characters into corresponding wide

characters for a wide character constant. A pointer to a copy of the locale is returned

by the function localeconv().

The equivalent type of a plain char is unsigned char.
