本文介绍了一个用于Cocos2d-x项目的字符集转换模块的实现细节，包括如何配置环境并使用iconv进行不同字符集之间的转换，特别关注于gbk到utf-8的转换过程。

环境配置：

./configure --host=arm-eabi

Android.mk

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := iconv_static
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 \

include $(BUILD_STATIC_LIBRARY)

int convert(const char *from_charset, const char *to_charset, const char *inbuf,
		size_t inlen, char *outbuf, size_t outlen) {
	iconv_t iconvH;
	iconvH = iconv_open(to_charset, from_charset);
	if (!iconvH)
		return false;
	memset(outbuf, 0, outlen);

#if(CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
	const char *temp = inbuf;
	const char **pin = &temp;

		return false;

		iconv_close(iconvH);
		return false;
	}
#endif
	iconv_close(iconvH);
	return true;
}

#endif
