It should not cause a problem unless you use a DOS character set.
In an ISO character set, the 32 characters starting at 128 are
control characters. I think there is an ISO character set for Greek.
The 128+27 character is a substitute for the ESC [ code which starts
an 8-bit ISO command sequence - for cursor control maybe.
