cocos2d-x 3.0rc1 使用iconv库 解决UTF8乱码问题
多国语言要用到开源字符转换 iconv
先贴出自己的使用代码 你能够做成头文件

//#endif注意设置安卓版本号的路径和win32版本号的路径
win32版本号是rc1版本号里面有的自带iocnv.h头文件和lib
可是Android版本号须要自己下载
1.下载
在windows上用iconv.dll。在IOS上系统有提供这个库。导入就能够，在android上要自己去下一个。
http://ftp.gnu.org/pub/gnu/libiconv/
这个是官网地址，眼下iconv最新版本号是1.14,2011.8.7版本号的。大小4.8M
官方地址：
http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
2.完成下载，解压放到E:\MyCocos\cocos2dx-workspace\hello\cocos2d文件夹下(这里是我自己的文件夹),改名为iconv,和cocos。extensions，external等同文件夹
3.在iconv文件夹下添加Android.mk文件，写入
LOCAL_PATH:= $(call my-dir) #libiconv.so include $(CLEAR_VARS) LOCAL_MODULE := iconv_static LOCAL_MODULE_FILENAME := libiconv LOCAL_CFLAGS := \ -Wno-multichar \ -DAndroid \ -DLIBDIR="c" \ -DBUILDING_LIBICONV \ -DIN_LIBRARY LOCAL_SRC_FILES := \ libcharset/lib/localcharset.c \ lib/iconv.c \ lib/relocatable.c LOCAL_C_INCLUDES += \ $(LOCAL_PATH)/include \ $(LOCAL_PATH)/libcharset \ $(LOCAL_PATH)/lib \ $(LOCAL_PATH)/libcharset/include \ $(LOCAL_PATH)/srclib include $(BUILD_STATIC_LIBRARY)
4. 在E:\MyCocos\cocos2dx-workspace\hello\proj.android\jniproject的Android.mk里改动，增加这个lib和include文件夹（以下的路径要依据项目实际情况改动）
$(LOCAL_PATH)/../../cocos2d/iconv/include \ $(LOCAL_PATH)/../../cocos2d/iconv/libcharset \ $(LOCAL_PATH)/../../cocos2d/iconv/lib \ $(LOCAL_PATH)/../../cocos2d/iconv/libcharset/include \ $(LOCAL_PATH)/../../cocos2d/iconv/srclib \ $(LOCAL_PATH)/../../cocos2d/iconv \ LOCAL_WHOLE_STATIC_LIBRARIES += iconv_static $(call import-module,iconv)下面是我自己的Android.mk文件里的代码 以后假设版本号变动能够參考这个代码来改
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := cocos2dcpp_shared
LOCAL_MODULE_FILENAME := libcocos2dcpp
LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes \

$(LOCAL_PATH)/../../cocos2d/iconv/srclib \
$(LOCAL_PATH)/../../cocos2d/iconv \
LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static
LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static
LOCAL_WHOLE_STATIC_LIBRARIES += iconv_static
include $(BUILD_SHARED_LIBRARY)
$(call import-module,2d)
$(call import-module,audio/android)
$(call import-module,Box2D)
$(call import-module,iconv)
5。
网上非常多教程都讲到这里。但实际上，假设这个时候进行编译。问题还一大堆。
1）iconv.h不存在，在ivonv/include/有 iconv.h.in, iconv.h.build.in，就是没看到iconv.h
把iconv.h.in改名成iconv.h。发现编译非常多错误
主要错误是类型不匹配，还有非常多@符号。
因此须要进行改动。主要改法是不存在的改成存在的。@符号去掉
以下是我自己改完之后的iconv.h文件。
编译OK.
