Thanks.. what I was looking for was:

"\ck" (which worked)

I had only come across \v which did not work.

I've been loading the contents of an Excel spread sheet (what was actually supposed to be just plain text), however it contained probably 50 random occurances of the vertical tab within 3000 rows of 50 columns. This character imparted a line break when inspecting DB rows in a terminal but was otherwise, invisible. I considered stripping everything exception a subset, but lots of uni-characters were necessary.

But, regarding my original question, is there some relationship between the non-printing character formatting used with "cat -vte <file>" and determining the correct character class to use in a regex?
