modifying the processed unicode value.

Hi,
This is on z/OS and perl-5.8.6.
--------------------------------------

U8 u, *s;

1: s++;

2: u &= ((len >= 6) ? 0x01 : (0x1F >> (len-2)));

3: uv = (((u) << 5)|(PL_e2utf[(U8)(*s)] &
((U8)0x1f)));
---------------------------------------

Before starting, s is set to "\x8a\x41" (utf-ebcdic
bytes equivalent to code point 192), u is set to
"\x8a" and len is set to 2 (no. of bytes in s).

After completing line 3, u =  \x0a, and uv = 320. 

Is there a way to get uv = 192 (\xC0) by modifying the
logic in lines 2 and 3 ? 

Thanks in advance,
Rajarshi.
