Questions tagged [ansistring]

An ANSI string is an array of 8 bit characters from the ANSI character set, a superset of the 7 bit ASCII character set, terminated by a binary zero. The ANSI string is primarily used in the C programming language and manipulated by a set of ANSI string functions provided by the C Standard Library. Most questions involving ansistring pertain to transformations to other character sets or other representations such as to UNICODE or std::string in C++.
