[syslog-ng] Syslog-ng relay: how to delete or modify special character ^M?

[alain.villefranque at orange.com]

Hi all,

I have an issue with the character Carriage Return (^M) inserted by the Syslog source machine.
I try to substitute or rewrite this special character with syslog-ng relay, but it is impossible to modify it, it seems this char is invisible for the program.
I've tried to modified it with either with ^M or 0xD char with no success.

Example of received message:

I'd like to suppress ^M or replace it with a "space" char.

Is there any specific action to do in order to modify ^M special character ?

Regards

Alain
