tomlplusplus/tests/manipulating_values.cpp
Mark Gillard ca6f639fb9 fixed narrowing conversion warnings when constructing int values from unsigned
also:
- added ability to construct values from wide strings and u8 strings
- added non-template version of array::is_homogeneous()
- added explicit instantiations for more template types when `!TOML_ALL_INLINE`
- cleaned up abi namespaces
- simplified build and test machinery on windows
- removed TOML_CHAR_8_STRINGS since it no longer makes sense
