runes are 16-bit numbers and thus byte-order dependent,
but /dev/snarf (and all other files) expect the utf8 encoding,
which is not byte-order dependent.  page /sys/doc/utf.ps.
print(2) generates utf8 and can print rune strings via %S,
so you can use

if((fd = open("/dev/snarf", OWRITE|OTRUNC)) >= 0){
    fprint(fd, "%.*S", RuneCnt, Buffer);
    close(fd);
}

Hello Fans

I write program for viewing character set and copy selected
characters to snarf, All work fine, but how i can put Rune to snarf.
Something like that don't work:

          if((fd=open("/dev/snarf",OWRITE|OTRUNC))>0)
          {
              write(fd,Buffer,sizeof(Rune)*RuneCnt);
              close(fd);
          }

Thanks
