So will the string command:
set xlateOutVals [string map {\T\ &} $xlateInVals]
I usually don’t like to use string commands on a list but since you are setting a list, its OK
FWIW, the string command isa bit more ergonomic when doing minor changes. Its more optimized and designed to do a specific task.
And, the nice thing is you don’t have to worry about escaping regular expression special characters
