Problem with ord () and string

i having this problem if i:

mychr = '';

where the "space" in mychr is equivalent to # 255 (manually entered by ALT + 255), and I write:

myord = ord (mychr)

to myord returns 160, not 255. Of course, the same problem is also with charater ALT + 254, etc. How can I solve this problem? I tested on delphi xe in console mode.

Note: if I use:

mychar = # 255;

then the ord () function will return the value correctly.
