question: private void writeUTFBody ( String s ) throws IOException { int len = s . length ( ) ; for ( int off = 0 ; off < len ; ) { int csize = Math . min ( len - off , CHAR_BUF_SIZE ) ; s . getChars ( off , off + csize , cbuf , 0 ) ; for ( int cpos = 0 ; cpos < csize ; cpos ++ ) { char c = cbuf [ cpos ] ; if ( c <= 0x007F && c != 0 ) write ( c ) ; else if ( c > 0x07FF ) { write ( 0xE0 | ( ( c > > 12 ) & 0x0F ) ) ; write ( 0x80 | ( ( c > > 6 ) & 0x3F ) ) ; write ( 0x80 | ( ( c ) & 0x3F ) ) ; } else { write ( 0xC0 | ( ( c > > 6 ) & 0x1F ) ) ; write ( 0x80 | ( ( c ) & 0x3F ) ) ; } } off += csize ; } }
target:  Writes the "body" (i.e., the UTF representation minus the 2-byte or 8-byte length header) of the UTF encoding for the given string.
