Also replaces the SFIANE tricks applied in ce7ecdb with conditional compilation. The code was too complicated along with the other trick to access private data members.

- Update of rootfile
- Changelog
9.1.0 - 2022-08-27
* ``fmt::formatted_size`` now works at compile time
`#3026 <https://github.com/fmtlib/fmt/pull/3026>`_
For example (`godbolt <https://godbolt.org/z/1MW5rMdf8>`__):
.. code:: c++
#include <fmt/compile.h>
int main() {
using namespace fmt::literals;
constexpr size_t n = fmt::formatted_size("{}"_cf, 42);
fmt::print("{}\n", n); // prints 2
}
* Fixed handling of invalid UTF-8
`#3038 <https://github.com/fmtlib/fmt/pull/3038>`_,
`#3044 <https://github.com/fmtlib/fmt/pull/3044>`_,
`#3056 <https://github.com/fmtlib/fmt/pull/3056>`_
* Improved Unicode support in ``ostream`` overloads of ``print``
`#2994 <https://github.com/fmtlib/fmt/pull/2994>`_,
`#3001 <https://github.com/fmtlib/fmt/pull/3001>`_,
`#3025 <https://github.com/fmtlib/fmt/pull/3025>`_
* Fixed handling of the sign specifier in localized formatting on systems with
32-bit ``wchar_t``
`#3041 <https://github.com/fmtlib/fmt/issues/3041>`_).
* Added support for wide streams to ``fmt::streamed``
`#2994 <https://github.com/fmtlib/fmt/pull/2994>`_
* Added the ``n`` specifier that disables the output of delimiters when
formatting ranges
`#2981 <https://github.com/fmtlib/fmt/pull/2981>`_,
`#2983 <https://github.com/fmtlib/fmt/pull/2983>`_
For example (`godbolt <https://godbolt.org/z/roKqGdj8c>`__):
.. code:: c++
#include <fmt/ranges.h>
#include <vector>
int main() {
auto v = std::vector{1, 2, 3};
fmt::print("{:n}\n", v); // prints 1, 2, 3
}
* Worked around problematic ``std::string_view`` constructors introduced in C++23
`#3030 <https://github.com/fmtlib/fmt/issues/3030>`_,
`#3050 <https://github.com/fmtlib/fmt/issues/3050>`_

`#3055 <https://github.com/fmtlib/fmt/issues/3055>`_

the default floating-point formatting
`#2984 <https://github.com/fmtlib/fmt/pull/2984>`_
* Fixed issues with floating-point formatting on exotic platforms.
* Improved the implementation of chrono formatting
`#3010 <https://github.com/fmtlib/fmt/pull/3010>`_
* Improved documentation
