Cocos2d-win32平台下中文乱码问题解决方案

  原因：Windows中文环境采用的是GBK编码，源程序文件默认也是GBK编码。

  解决方案：使用配置方式读取中文字。

只有在Windows平台下才会出现这种问题，Android和IOS不会出现这个问题。

解决方案

  引入cJson开源库，通过读取utf-8编码格式的json文件进行显示。

效果展示

源码如下

json文件

HelloWorldScene.h

#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__#include "cocos2d.h"
//引入string库
#include <string>
//引入cJson库文件
#include "cJSON.h"class HelloWorld : public cocos2d::Scene
{
public:static cocos2d::Scene* createScene();virtual bool init();// implement the "static create()" method manuallyCREATE_FUNC(HelloWorld);private://记录当前文字内容std::string prt_content;cocos2d::Label* prt_label;
};#endif // __HELLOWORLD_SCENE_H__

HelloWorldScene.cpp

#include "HelloWorldScene.h"
#include "SimpleAudioEngine.h"USING_NS_CC;
using namespace std;Scene* HelloWorld::createScene()
{return HelloWorld::create();

{printf("Error while loading: %s\n", filename);printf("Depending on how you compiled you might have to add 'Resources/' in front of filenames in HelloWorldScene.cpp\n");
}// on "init" you need to initialize your instance
bool HelloWorld::init()

}

TIPS：setDimensions使用英文可能失效，这是引擎级别的bug，从Cocos官方论坛得知该结论。
