I am not getting an error...

Before the function call I using the ASCII(RIGHT(t.OffensiveColumn,1)) to see what the ASCII character is, then calling the function, and returning the results to a temp table. Then on my temp table, the column that the function was on, I am running the ASCII(RIGHT(r.RemovedASCII) and the values values are the same.

Starting ASCII value 68 - ASCII values after function call is 68.
