Provides an ANSI to UTF8 reciprocal function for SQLite3 _sqlite

That must be used when using Sqlite3.

How to use:

char* src = "...";//ANSI or UTF8 string to be converted
char* DST = null;//saves memory pointers allocated internally by functions and does not require incoming memory buffers

Convert to Utf-8:to_utf8 (SRC, &DST);
Convert to ANSI:TO_GB (SRC, &DST);

Return value: 0-Failed, non 0-successful.
Note: If the operation succeeds, you need to manually free the space allocated within the function:

Copy Code code as follows:

if (DST)
{
Free (DST);
DST = NULL;
}

Code:

Copy Code code as follows:

#include <windows.h>
#include <stdio.h>int To_utf8 (char* psrc, char** ppdst)
{
int Ret,ret2;
wchar_t* PWS = NULL;
char* Putf = NULL;

ret = MultiByteToWideChar (CP_ACP, 0, PSRC,-1, NULL, 0);
if (ret<=0) {
*PPDST = NULL;
return 0;
}
PWS = (wchar_t*) malloc (ret*2);
if (!PWS) {
*PPDST = NULL;
return 0;
}
MultiByteToWideChar (CP_ACP, 0, PSRC,-1, PWS, ret);
Ret2 = WideCharToMultiByte (Cp_utf8, 0, PWS,-1, NULL, 0, NULL, NULL);
if (ret2<=0) {
Free (PWS);
return 0;
}
Putf = (char*) malloc (Ret2);
if (!PUTF) {
Free (PWS);
return 0;
}
if (WideCharToMultiByte (Cp_utf8, 0, PWS, ret, PUTF, ret2, NULL, NULL)) {
