I have an issue regarding it that while i can read the unicode data if it is in file but when it is in terminal it can't read the unicode data here is the code i created#include <iostream> #include <locale> #include <string_view> int main() { std::locale user(""); std::locale unicode("en_US.UTF8"); const auto str = std::string(u8"This! Is a tešt тест ** % test."); auto & decoder = std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t>>(unicode); auto & encoder = std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t>>(user); auto inmb = std::mbstate_t(); auto outmb = std::mbstate_t(); auto * next = str.data(); const auto * endptr = str.data() + str.size(); for (auto * ptr = str.data(); ptr < endptr; ptr = next) { wchar_t value; wchar_t * unusedA; decoder.in [1](inmb, ptr, endptr, next, &value, &value + 1, unusedA); char buffer[4]; char * endbuffer; const wchar_t * unusedB; encoder.out(outmb, &value, &value + 1, unusedB, &buffer[0], &buffer[4], endbuffer); std::cout <<std::string_view(buffer, endbuffer-buffer) <<" : " <<std::boolalpha <<std::isalpha(value, unicode) <<std::endl; } return 0; } Any suggestions would be appreciated :)
Check your locale ? F. _______________________________________________ Apertium-stuff mailing list Apertium-stuff@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/apertium-stuff
