Not quite.  What was most likely happening is that your shell was
interpreting the "&" character for you (to put the command to that point
into background), and you needed to escape it to prevent this from
happening.  Xymon didn't take care of these for you, it simply doesn't use
special characters, other than the space character, in this context.

It's unlikely that the "?" needed escaping on the command line.  A "?"
causes the shell to try a glob match on a filename, but you probably don't
have a filename matching "cont=...?..." and so it didn't expand to anything
when not escaped.  In the shell, "\?" is treated the same as "?" if there
is no glob match, which is why it worked.

When I looked at the dump the escapes were being passed straight through.

Glad to hear it.

Ah yes.  When computers try to be helpful, they don't always succeed.
