You misunderstand. "Chevrons" or "guillemets" (sometimes called
"Euroquotes") refer to the double angle brackets, Ascii-174 and
-175, used to embedd formatting statements. Used this way, i.e., in
1-byte, "active" form, they are control characters, and can't be
displayed (except in eXPanded view) or printed in XyWrite. To get
displayable, printable ("inactive", non-control-character) chevrons,
you need to use the 3-byte form of these characters, {255}AE and
{255}AF, which display and print (in XyWrite only) as Ascii-174 and
-175. These 3-byte forms are produced by holding down the Shift,
Alt and Ctrl keys and pressing 1,7,4 or 1,7,5. (Some keyboard files
use another combination of shift keys, e.g., Ctrl-Alt or Shift-
Ctrl.)

My only point was that the first byte of these 3-byte characters is
Ascii-255, one of the high-order Ascii characters that do not
transmit reliably via e-mail without some kind of encoding.

None of this has anything to do with CrLf's.
