Help with Escape Characters in OBX

We put in a fix to change / to an Escape Character when the transcription used the wrong slash.

# This line replaces any instances of a backslash with the HL7 escape sequence

regsub -all \B $xlateInVals \E\ xlateOutVals

Now the same message is coming with true Escape Characters:

DICTATED HISTORY: E||

which translates like this:

E E DICTATEDE HISTORY:E EEEEE< I need to accomodate both situations, but I can’t seem to figure out how to do it. Any help would be appreciated.
