ARENE_NATIVE_CHAR8_T

#define ARENE_NATIVE_CHAR8_T

A platform support query for testing if __cpp_char8_t is defined.

Usage:

#if ARENE_IS_ON(ARENE_NATIVE_CHAR8_T)

The value of this query is determined as follows, in order of precedence:

1. If ARENE_NATIVE_CHAR8_T has been explicitly defined via a -D flag to the compiler or similar:
   • ARENE_ON if it is truthy
   • ARENE_OFF if it is not truthy

1. If __cpp_char8_t is defined it is ARENE_ON_BY_DEFAULT

1. Otherwise, it is ARENE_OFF_BY_DEFAULT

ARENE_NATIVE_CHAR8_T_I_

#define ARENE_NATIVE_CHAR8_T_I_   ARENE_OFF_BY_DEFAULT
