\ doesn't work in tc()"

Issues
1

The escaped quote doesn't work and is considered as a proper quote, thus breaking any formula.

2

On sh too. I'm trying to run awk script and getting this error:

err: a literal can't follow another literal

Do you try with "My Personal " FIX" :

Add "+tc(utf, "22")+", between your double Quoted Expression, where you need one char ".
