[好惆怅啊]TCL编码转换的问题

    我的头文件和库文件都是从编译TCLSH84里提取出来的,但嵌入到C++中后可选择的编码类型就剩下utf-8 identity unicode这三个了,但TCLSH84.exe里却有很多.因为编码不同,处理中文的时候就得转换,查了下手册,里面说用Tcl_ExternalToUtf()可以完成这个功能,但试了好几次还是乱码 =.=|||  不知道是不是我用法错了(哪位有sample的话让我参考下吧).

最后在网上看到用encoding convertfrom identity $str来转换编码.结果确实很好,代码如下:

 1#include "Program.h"
 2#include <tcl/tcl.h>
 3#include <string>
 4
 5using namespace std;
 6
 7int main()
 8{
 9    string text = "df今天的天气传说是不错的好像。df";
10    string code = "set text [encoding convertfrom identity $text] \n set ret [string range $text 1 5]";
11
12    Tcl_Interp *interp = Tcl_CreateInterp();
13
14    // get all encoding name
15      Tcl_GetEncodingNames(interp);  
16    cout << Tcl_GetStringResult(interp) << endl;
17
18    // setup parameters
19    assert(Tcl_SetVar(interp, "text", text.c_str(), TCL_GLOBAL_ONLY));
20    assert(Tcl_SetVar(interp, "ret", "", TCL_GLOBAL_ONLY));
21
22    // eval script
23    Tcl_Eval(interp, code.c_str());
24
25    // get result
26    char *ret;
27    ret = (char *)Tcl_GetVar(interp, "ret", TCL_GLOBAL_ONLY);
28
29    cout << "ret:" << ret << endl;
30
31    system("pause");
32
33    Tcl_DeleteInterp(interp);
34}

    但当我在MFC中用的时候却又出现乱码了...太不解了...大家给帮帮忙吧:

 1UINT CHTMLVampireDlg::HttpRequestFunc(LPVOID pParam)
 2{
 3    CHTMLVampireDlg *dlg = (CHTMLVampireDlg*)pParam;
 4    CString url;

11        CString htmlCode, tmpStr;
12        CHttpFile* file = con->OpenRequest(CHttpConnection::HTTP_VERB_GET, "");
13        file->SendRequest();
14        while(file->ReadString(tmpStr))
15        {
16            htmlCode += tmpStr;
17        }

19        /**////* 当网页编码为utf-8时启用如下代码 */

25        //wbuffer = new wchar_t[wbufferLen];
26        //memset(wbuffer, 0, sizeof(wchar_t)*wbufferLen);

33        //memset(ascii, 0, sizeof(char)*asciiLen);

35        
36        dlg->richEdit_htmlCode.SetWindowText(htmlCode);
37        //delete[] ascii;
38
39        //delete[] wbuffer;

41        file->Close();
42        delete file;
43        con->Close();
44        delete con;
45        session.Close();
46
47    }
48    catch(CInternetException* excep)
49    {
50        CString errMsg;
51        excep->GetErrorMessage((LPTSTR)(LPCTSTR)errMsg, 0);
52        dlg->SetWindowText(url + "  " + errMsg);
