How about std::wstring?

[z16166]

Your lib is quite elegant.

Usually I use std::wstring in memory to support case-insensitive comparison/search. UTF8 string is not good for such scenarios.

Would you please add std::wstring support? We usually use Windows API to convert between UTF8/wchar_t for Windows, and use libiconv for Linux/macOS. Thanks.

i have never worked with std::wstring.

a quick search found this approach for converting to/from utf8/wchar_t:

#include <locale>
#include <codecvt>
#include <string>

std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
std::string narrow = converter.to_bytes(wide_utf16_source_string);
std::wstring wide = converter.from_bytes(narrow_utf8_source_string);

would there be any downsides using this approach over Windows API and libiconv?

C++ codecvt is deprecated. Anyway it still can be compiled and convenient, compared to libiconv、ICU.
