/**
 * @defgroup apr_cstr C (POSIX) locale string functions
 * @ingroup apr_strings
 *
 * The apr_cstr_* functions provide traditional C char * string text handling,
 * and notabilty they treat all text in the C (a.k.a. POSIX) locale using the
 * minimal POSIX character set, represented in either ASCII or a corresponding
 * EBCDIC subset.
 *
 * Character values outside of that set are treated as opaque bytes, and all
 * multi-byte character sequences are handled as individual distinct octets.
 *
 * Multi-byte characters sequences whose octets fall in the ASCII range cause
 * unexpected results, such as in the ISO-2022-JP code page where ASCII octets
 * occur within both shift-state and multibyte sequences.
 *
 * In the case of the UTF-8 encoding, all multibyte characters all fall outside
 * of the C/POSIX range of characters, so these functions are generally safe
 * to use on UTF-8 strings. The programmer must be aware that each octet may
 * not represent a distinct printable character in such encodings.
 *
 * The standard C99/POSIX string functions, rather than apr_cstr, should be
 * used in all cases where the current locale and encoding of the text is
 * significant.
