Hey mark!

I recall reading that and at the time finding absolutely zero references to
back that up.  I just tried again with no success.  I am not sure where that
idea comes from and the closest I could find is the well documented c1 control
codes.  It wouldn't surprise me if there was some propietary usage for 0x8d as
a soft line break but finding a reference to back it up is a bit of a challenge
 if not indeed impossible.

 ml> not sure how that will come out because it is being interpreted

I 'see' it as a nonprintable 8 bit character corresponding to 0x8d which is
indeed a c1 control code.  Converting it to utf-8 from cp437 yields the
character in question which in 8 bit hex-speak corresponds to the two bytes
c3ac as demonstrated below;

-={ '<Esc>:read !echo -e "\u00ec is the same as \xc3\xac"' starts }=-
ì is the same as ì
-={ '<Esc>:read !echo -e "\u00ec is the same as \xc3\xac"' ends }=-

It is too easy.

Life is good,
Maurice
