Foreign and special character codes showing in XY4

["Paul Breeze" dmarc-noreply@xxxxxxxx (Redacted sender "paul.breeze" for DMARC)]

When running XY4 in Windows XP (under VDOS or without VDOS), when I
insert an accented character such as é it is accompanied by its code
enclosed in square brackets [XXX], in page and draft views. However the
code does not appear in expanded view. In Windows 7 the code does not
appear in any view, simply the accented character. I would like to be
able to suppress the codes when running under Windows XP but I have been
able to glean no clue as to why they appear under one operating system
and not the other. Does anybody have any insight into this?

Thanks

Paul
