Hi. You can use 'iconv' for recode a string into another encoding. For
that you must use 'iconv_open' and 'iconv_close' for open an close a
handler for recode (use man iconv_open and man iconv_close for help).
Later, for recode the string you must use function 'iconv' (man 3 iconv
for help), but, for better help, consult internet to view examples
because use directly that funcion is incorrect and won't obtain the
results what you want. I put an example here:
string Convert::convert(const string &text) const
{
; iconv(_con, NULL, NULL, NULL, NULL); ; ;
// Necessary at beggining
; size_t enterSize = text.size();
; size_t exitSize = enterSize * 2; ; ; ;
// The maximum size will be the double than the sou
; char *ex = (char*)malloc(exitSize * sizeof(char) + 1); ;
// Allocating memory
; char *exit = ex; ; ; ; ;
// Aux
; #ifdef __WIN32__
const char *enter = (const char*)text.c_str();
; #else
char *enter = (char*)text.c_str();
#endif
; memset(exit, 0, exitSize); ; ; ; ;
// Setting all bytes the value 0
; size_t res = iconv(_con, &enter, &enterSize, &ex,
&exitSize); // Converting
if (res == (size_t)(-1)) ; ; ;
// If the function 'iconv' can't convert --> error
; throw(ConvertException::CONVERT);
; string ret(exit, ex - exit);
; free(exit); ; ; ; ;
// Freeing memory
; return ret;
}
(Sorry, but I use C++, but the utilization is the same).
Where '_con' is the handler used with 'iconv_open'. That code works on
Windows and Linux.
I hope that instructions serve you.
