cocos2d-x 3.2文字显示，添加汉字

//下面这段代码添加到init里面
CCMenuItemFont::setFontSize(32);    //设置字号  
    CCMenuItemFont::setFontName("Marker Felt"); //设置字体  
	CCMenuItemFont *font1=CCMenuItemFont::create("hah",this,menu_selector(MainUI::menuChangeStart));//添加文字按钮，点击实现缩放  
    font1->setColor(ccc3(255,0));  //设置颜色  
      
	CCMenuItemToggle * font2=CCMenuItemToggle::createWithTarget(this,menu_selector(MainUI::menuChangeSet),CCMenuItemFont::create("on"),CCMenuItemFont::create("off"),NULL);   //添加选择按钮，点击实现on与off之间切换  
    font2->setColor(ccc3(0,255,0));  
    font2->setSelectedIndex(1);    //设置默认显示，从零算起（此为off）  
      
    CCMenu *newmenu=CCMenu::create(font1,font2,NULL);  // 此步很关键，否则只是菜单项，但不能点击  
    newmenu->setPosition(ccp(visibleSize.width/2,visibleSize.height/2));  
    newmenu->alignItemsVertically();     //设置为竖排排列  
    this->addChild(newmenu,2);  

修改文字

	label = LabelTTF::create("Last button: None","Marker Felt",32);
	label->setPosition(Point(winSize.width / 2,winSize.height - 80));
	label->setHorizontalAlignment(TextHAlignment::CENTER);
	this->addChild(label);

label->setString("Last button: * ");

引用类库

1，在你的工程中添加对头文件cocos2dxplatformthird_partywin32iconviconv.h的引用。
2，相应的库引用：cocos2dxplatformthird_partywin32librarieslibiconv.lib。

添加汉字

先添加这两个转换函数

inline void HelloWorld::WStrToUTF8(std::string& dest,const std::wstring& src){
dest.clear();
for (size_t i = 0; i < src.size(); i++){
wchar_t w = src[i];
if (w <= 0x7f)
dest.push_back((char)w);
else if (w <= 0x7ff){
dest.push_back(0xc0 | ((w >> 6)& 0x1f));
dest.push_back(0x80| (w & 0x3f));
}
else if (w <= 0xffff){
dest.push_back(0xe0 | ((w >> 12)& 0x0f));
dest.push_back(0x80| ((w >> 6) & 0x3f));
dest.push_back(0x80| (w & 0x3f));
}
else if (sizeof(wchar_t) > 2 && w <= 0x10ffff){
dest.push_back(0xf0 | ((w >> 18)& 0x07)); // wchar_t 4-bytes situation
dest.push_back(0x80| ((w >> 12) & 0x3f));
dest.push_back(0x80| ((w >> 6) & 0x3f));
dest.push_back(0x80| (w & 0x3f));
}
else
dest.push_back('?');
}
}
//! simple warpper
inline std::string HelloWorld::WStrToUTF8(const std::wstring& str){
std::string result;
WStrToUTF8(result,str);
return result;
}

std::string text = WStrToUTF8(L"你好世界");
		auto label = LabelTTF::create(text,"Arial",24);
		label->setPosition(Point(200,200));
		this->addChild(label);
