dep/anitomy: port to use UCS-4 rather than wide strings rationale: wide strings are not the same on every platform, and might not even be Unicode. (while they usually are, its possible that they are not) I was *going* to change StringToInt to use a string stream, but outputting to an integer doesn't seem to work at all with UCS-4, even though it ought to, so I just rolled my own that uses the arabic digits only.

// Header-only configuration test

#include "fmt/core.h"
#include "fmt/ostream.h"
#include "gtest/gtest.h"

#ifndef FMT_HEADER_ONLY
#  error "Not in the header-only mode."
#endif

TEST(header_only_test, format) { EXPECT_EQ(fmt::format("foo"), "foo"); }
