Can more character types be supported? Such as wchar_t, char8_t, char16_t, char32_t

[aSurgingRiver]

The software library supports the char character type by default.
Using wchar_t character type instantiation will result in an error.

basic_json<std::map, std::vector, std::wstring>

The library uses a large number of char instantiations in serialization and deserialization. This causes a mismatch with the wchar_t type.

The library's internal string storage is UTF-8 based, so StringType needs a char-compatible value type; std::wstring/char16_t/char32_t-based strings can't be used directly as StringType. You can still parse/store wide-character data by converting to/from UTF-8 first — see the FAQ's 'Wide string handling' section (https://json.nlohmann.me/home/faq/#wide-string-handling) for a std::wstring example using codecvt_utf8. char8_t is supported for the _json/_json_pointer literals as of recent versions.
