Thanx a lot. I only need the decode Part of it . We fight with ä, ü and ö (German). I will test some use cases, which we need. I also so some error checking for our purpose. You’ve saved my day

i don’t quite understand the changes of Rodrigo and as far as i see , the modifications are not in your code. I have no example to proof the changes of Rodrigo. Do you modify your downloadable code ?

Kind regards

“Olá Mundo”

i found bug in this function: xml_utf8_encode

i change to:

static char *xml_utf8_encode(const char *s, int len, int *newlen,
const XML_Char *encoding)
{
int pos = len;
int size;
char *newbuf;
unsigned int c;
unsigned short (*encoder)(unsigned char) = NULL;
xml_encoding *enc = xml_get_encoding(encoding);

*newlen = 0;
if (enc)
encoder = enc->encoding_function;
else
/* If the target encoding was unknown, fail */
return NULL;

if (encoder == NULL) {
/* If no encoder function was specified, return the data as-is.
*/
newbuf = (char*)emalloc(len + 1);
memcpy(newbuf, s, len);
*newlen = len;
newbuf[*newlen] = ”;
return newbuf;
}

/* This is the theoretical max (will never get beyond len * 2 as long
* as we are converting from single-byte characters, though) */
size=len;
newbuf = emalloc(size);
while (pos > 0) {
c = encoder ? encoder((unsigned char)(*s)) : (unsigned short)(*s);
// alteredo, se o tamanho do novo buffer size ) {
size+=16; // add 16 bytes in new buffer
newbuf = (char*)erealloc(newbuf, size);
}
if (c < 0×80)
newbuf[(*newlen)++] = (char) c;
else if (c > 6));
newbuf[(*newlen)++] = (0×80 | (c & 0×3f));
}
else if (c > 12));
newbuf[(*newlen)++] = (0xc0 | ((c >> 6) & 0×3f));
newbuf[(*newlen)++] = (0×80 | (c & 0×3f));
}
else if (c > 18));
newbuf[(*newlen)++] = (0xe0 | ((c >> 12) & 0×3f));
newbuf[(*newlen)++] = (0xc0 | ((c >> 6) & 0×3f));
newbuf[(*newlen)++] = (0×80 | (c & 0×3f));
}
pos–;
s++;
}

newbuf[*newlen] = 0;
//newbuf = erealloc(newbuf, (*newlen)+1);
return newbuf;
}

and now work fine!

Thank you

create this function:

void utf8_clean(void *ptr)
{
if ( ptr ) free(ptr);
}

using:

#include “utf8.h”

int main(int argc, char **argv)
{
char *iso_str = “Pontus Östlund”;
char *utf8_str;

utf8_str = utf8_encode(iso_str);
iso_str = utf8_decode(utf8_str);
utf8_clean( utf8_str );
utf8_clean ( iso_str );

return 0;
}
