Provides an ANSI to UTF8 Conversion Function for SQLite3

Required when using Sqlite3

Usage:

Char * src = "..."; // ANSI or UTF8 string to be converted
Char * dst = NULL; // Save the memory pointer internally allocated by the function.

Convert to UTF-8: to_utf8 (src, & dst );
Convert to ANSI: to_gb (src, & dst );

Returned value: Zero-failed, non-zero-successful.
Note: If the operation is successful, you need to manually release the space allocated within the function:

Copy codeThe Code is as follows:
If (dst)
{
Free (dst );
Dst = NULL;
}
