Thanks a lot, helas there is MANY things around UTF-8: source file encoding, option in VS, command lines options (very funny: # are no more alloweded), locale parameters. I m making many tests, but it still doesnt displays my special characters.
for the moment, i m just trying a test with
myFont->drawString(ofToString("test UTF8: é à è"), 200,200);
but i have only on screen test UTF8 printed
this page was sounding the most significant , without result:
i m sure i m not alone facing this puzzling problem, is there any step by step to solve this ?
