方法1:
在网上查看的推荐方法(C++代码),但没解决我遇到的问题;
CPLSetConfigOption("GDAL_FILENAME_IS_UTF8", "NO");// 中文路径问题
CPLSetConfigOption("SHAPE_ENCODING", "");// 属性表乱码
方法2:
1.通过在线网网站,查看编码
https://wrtools.top/coderepair.php
现在乱码的utf-8,原本gbk是正常的,那就将utf-8转换成gbk编码问题就解决了。
2.参考C++中gbk和utf8互相转换文章
原文链接:C++实现utf8和gbk编码字符串互相转换
不同系统或者服务器之间消息传递经常遇到编码转换问题,这里用C++实现了一个轻量的gbk和utf8互相转换,可跨平台使用。(重量级的可以用libiconv库)
在windows下用<windows.h>头文件里的函数进行多字节和宽字符转换,linux下采用<iconv.h>头文件里的函数进行编码互相解析。
代码
#include <iostream>
#include <string>
#include <string.h>
#include <stdlib.h>
using namespace std;
#ifdef _WIN32
#include <windows.h>
string GbkToUtf8(const char *src_str)
{
int len = MultiByteToWideChar(CP_ACP, 0, src_str, -1, NULL, 0);
wchar_t* wstr = new wchar_t[len + 1];
memset(wstr, 0, len + 1);
MultiByteToWideChar(CP_ACP, 0, src_str, -1, wstr, len);
len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);
char* str = new char[len + 1];
memset(str, 0, len + 1);
WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL);
string strTemp = str;
if (wstr) delete[] wstr;
if (str) delete[] str;
return strTemp;
}
string Utf8ToGbk(const char *src_str)
{
int len = MultiByteToWideChar(CP_UTF8, 0, src_str, -1, NULL, 0);
wchar_t* wszGBK = new wchar_t[len + 1];
memset(wszGBK, 0, len * 2 + 2);
MultiByteToWideChar(CP_UTF8, 0, src_str, -1, wszGBK, len);
len = WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, NULL, 0, NULL, NULL);
char* szGBK = new char[len + 1];
memset(szGBK, 0, len + 1);
WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, szGBK, len, NULL, NULL);
string strTemp(szGBK);
if (wszGBK) delete[] wszGBK;
if (szGBK) delete[] szGBK;
return strTemp;
}
#else
#include <iconv.h>
int GbkToUtf8(char *str_str, size_t src_len, char *dst_str, size_t dst_len)
{
iconv_t cd;
char **pin = &str_str;
char **pout = &dst_str;
cd = iconv_open("utf8", "gbk");
if (cd == 0)
return -1;
memset(dst_str, 0, dst_len);
if (iconv(cd, pin, &src_len, pout, &dst_len) == -1)
return -1;
iconv_close(cd);

return 0;
}
int Utf8ToGbk(char *src_str, size_t src_len, char *dst_str, size_t dst_len)

char **pout = &dst_str;
cd = iconv_open("gbk", "utf8");
if (cd == 0)
return -1;
memset(dst_str, 0, dst_len);
if (iconv(cd, pin, &src_len, pout, &dst_len) == -1)
return -1;
iconv_close(cd);
*pout = '\0';
return 0;
}
#endif
int main(void)
{
char *src_str = "葡萄美酒夜光杯";
cout << "origin string: " << src_str << endl;
#ifdef _WIN32
// windows default is gbk
string dst_str = GbkToUtf8(src_str);
cout << "gbk to utf8: " << dst_str << endl;

char dst_gbk[1024] = {0};
Utf8ToGbk(src_str, strlen(src_str), dst_gbk, sizeof(dst_gbk));

GbkToUtf8(dst_gbk, strlen(dst_gbk), dst_utf8, sizeof(dst_utf8));
cout << "gbk to utf8: " << dst_utf8 << endl;
#endif
return 0;
}
gdal示例代码
const char* value = pFeature->GetFieldAsString(i);// 获取到的乱码字段值
string dst_str = Utf8ToGbk(value); // utf-8转换成gbk
std::cout << dst_str << std::endl;
