Compile-time Format String Checks
---------------------------------
Compile-time checks are enabled when using ``FMT_STRING``. They support built-in
and string types as well as user-defined types with ``constexpr`` ``parse``
functions in their ``formatter`` specializations.
Compile-time checks are supported in C++14 and up. They are enabled when using
``FMT_STRING`` and support built-in and string types as well as user-defined
types with ``constexpr`` ``parse`` functions in their ``formatter`` specializations.
``FMT_STRING`` may function in C++11 environments, but is not supported and can
produce illegible error messages. It is also known to fail in GCC when passing zero arguments.
