In this web page:
http://en.cppreference.com/w/cpp/locale/toupper
I got this code:
#include <iostream>
#include <cwctype>
#include <locale>
int main()
{
wchar_t c = L'\u017f'; // Latin small letter Long S ('ſ')
std::cout << std::hex << std::showbase;
std::cout << "in the default locale, toupper(" << (std::wint_t)c << ") =
"
<< std::toupper(c, std::locale()) << '\n';
std::cout << "in Unicode locale, toupper(" << (std::wint_t)c << ") = "
<< std::toupper(c, std::locale("en_US.utf8")) << '\n';
}
Which compiles like this:
g++.exe -Wall -fexceptions -g -m64 -std=gnu++14 -D_UNICODE -D_WIN32 -march=core2
-pedantic -std=c++11 -m64 -std=gnu++14 -D_UNICODE -D_WIN32 -IC:\dev\jme -c
C:\tmp\localetest01\main.cpp -o obj\Debug\main.o
g++.exe -o bin\Debug\localetest01.exe obj\Debug\main.o -lwinmm -lwinmm
Output file is bin\Debug\localetest01.exe with size 108.41 KB
Process terminated with status 0 (0 minute(s), 0 second(s))
0 error(s), 0 warning(s) (0 minute(s), 0 second(s))
Then I get a popup box with this message
---------------------------
localetest01.exe - System Error
---------------------------
The program can't start because libgcc_s_seh-1.dll is missing from your
computer. Try reinstalling the program to fix this problem.
---------------------------
OK
---------------------------
Which does not make sense since my compiler's exceptions are 'sjlj', go
figure!
I click OK, and then a cmd terminal comes saying:
int he default locale. touppor(0x17f) = 0x17f
terminate called after throwing an instance of 'std::runtime_error'
what(): locase::facet::_S_reate_c_locale name not valid
