Hi,

I read the Game Title from PARAM.SFO, which is in UTF-8. I need to convert it into Unicode. Please note that I deal with multi-byte characters in game title (Chinese/Japanese etc.) Please help me what are the library functions available to do this conversion.
I tried mbstowcs with setlocale(LC_ALL, "UTF-8"), but doesn't work. I tried to use iconv, but I can't find the necessary lib file in my build environment (with PSPToolchain).

Thanks,
Kiran

UTF-8 to unicode conversion is simple (from libccc which is used by intraFont):
Code:
int cccUTF8toUCS2(cccUCS2 * dst, size_t count, cccCode const * str) {
   if (!str || *str == '\0' || !dst) return 0;

    int i = 0, length = 0;
    while (str[i] && length < count) {
      if  (str[i] <= 0x7FU) {       //ASCII
         dst[length] = (cccUCS2)str[i];
         i++;    length++;
      } else if (str[i] <= 0xC1U) { //part of multi-byte or overlong encoding ->ignore
         i++;         
      } else if (str[i] <= 0xDFU) { //2-byte
         dst[length] = ((str[i]&0x001fu)<<6) | (str[i+1]&0x003fu);
         i += 2; length++;
      } else if (str[i] <= 0xEFU) { //3-byte
         dst[length] = ((str[i]&0x001fu)<<12) | ((str[i+1]&0x003fu)<<6) | (str[i+2]&0x003fu);
         i += 3; length++;
      } else i++;                    //4-byte, restricted or invalid range ->ignore
   }
    return length;
}
The library also supports common codepages (Big5,...)
Cheers, BenHur
