C++使用wstring拆分unicode分隔的字符串

Question

我正在尝试完成主题任务，但我的代码没有拆分。这是主要功能:

#define SQL_TEXT Latin_Text
#include <iostream>
#define SQL_TEXT Latin_Text
#include <sqltypes_td.h>
#include "Split.h"
#include <string>
#include <stdio.h>
#include <vector>
#include <cstring>

using namespace std;
int main ()
{
    VARCHAR_LATIN *result = new VARCHAR_LATIN[512];
    wchar_t *s1 = (wchar_t *)"Myýnameýisýzeeshan";
    **splitstringwc s(s1);
vector<wstring> flds = s.splitwc((wchar_t)'ý');**
    wstring rs = flds[1];
    wcout<<rs<<endl;
for (int k = 0; k < flds.size(); k++)
        cout << k << " => " << flds[k].data() << endl;

    cout<<result;
    return 0;
}

splitstringwc类的代码如下:

public:
splitstringwc(wchar_t *s) : wstring(s) { };
vector<wstring>& splitwc(wchar_t delim, int rep=0);
};


vector<wstring>& splitstringwc::splitwc(wchar_t delim, int rep) {
if (!flds1.empty()) flds1.clear();  // empty vector if necessary
wstring ws = data();
wcout<<ws<<endl;
//wcout<<delim<<endl;

//wstring ws;
//int j = StringToWString(ws, work);
wstring buf = (wchar_t *)"";
int i = 0;
while (i < ws.size()) {
    if (ws.at(i) != delim)
        buf += ws.at(i);
    else if (rep == 1) {
        flds1.push_back(buf);
        buf = (wchar_t *)"";
    } else if (buf.size() > 0) {
        flds1.push_back(buf);
        buf = (wchar_t *)"";
    }
    i++;
}
if (!buf.empty())
    flds1.push_back(buf);
return flds1;

代码不拆分输入字符串，当我尝试调试时，我在以下位置遇到段错误:wstring ws = data();

请帮忙....................

使用 strtok 而不是我自己的拆分函数，是根据 unicode 分隔符拆分字符串。

代码如下:

str = "Myýnameýisýzeeshan";
char *pch;
pch = strtok(str, "ý");
while (pch != NULL)
{
    printf("%s\n", pch);
    pch = strtok(NULL, "ý");
}

请注意，str 由由 UNICODE 分隔符分隔的 ANSI 字符串组成。
