SunOS - version upgrade - Control Characters

Hi,

We have a scenario of OS upgrade and in a simialr upgrade last time, we noticed a few stray bytes appearing and it resulted in application programs failing.....

Could you please share your expertise in removing such control characters in input/output files, to keep the ball rolling in short term and work with SunOS and/or App vendor for a permanent fix.

thanks.

Huh?

What Solaris release are you upgrading to what version and how?

Where precisely do these "stray bytes" do appear?
