after googling find useful function mbstowcs() used convert multibyte string wide-character string.

below example this.

{     wchar_t buf[255];     mbstowcs(buf,(const char*)name,name.getlength()+1);      byte bytes[255];     size_t length = wcslen(buf);     (size_t = 0; < length; i++)     {       bytes[i*2] = buf[i] >> 8;       bytes[i*2+1] = buf[i] & 0xff;     }   }
