problems using libiconv

[Genty Jean-Paul]

Hi 

 I wish to convert a ISO-8859-6 string to UTF-8.
I use iconv_string shipped with libiconv.

To simplify my initial string is 
szArabic[0]= 0x0D;
szArabic[1]= 0x0D;
szArabic[2]= 0x0D;
szArabic[3]= 0x00;

The arabic letter DAD ( 214 ) is repeated three times in my string .
Have an eye on http://www.langbox.com/codeset/iso8859-6.html to see
what it looks like.

My program looks like this

size_t iSizeOut = 0;  
char *ptrSaveUTF8Out = NULL;
iReturnIconv = iconv_string("ISO-8859", "UTF-8",
                 (const char *)szArabic,
                szArabic + strlen(szArabic) + 1,
                &ptrSaveUTF8Out,&iSizeOut);

My problem is that iconv_string returns -1 ( first call to iconv in
iconv_string source ).

                    Anyone has an idea on the correct use of
iconv_string ( and iconv by the way )  ???

 Thanks a lot
