i know that you can encode any codepoints of UTF16 or UTF32 in UTF8 which will handle everything possible in unicode .

It will show error I think since string can’t hold one codepoints of multibytes ! but using auto txt = u8”arabic ع”; on windows i always prefer to use wchar_t which will handle arabic characters well, than just encoded it in utf8

Arabic characters supported in UTF-16 not in UTF-8 and string is a typedef of basic_string<char> and it is takes only one byte . Instead , use std::u16string txt = u”وعليكم السلام”;
