I don't think the character based offsets can be avoided here. The nodes don't provide getter functions for all the locations I'm interested in and I have to construct the appropriate source location myself. I will try what you suggest and see how it goes.
I tried doing things with just `ExplicitCastExpr` initially and when I added test cases for the functional and C-style casts, I needed to do different replacement ranges.
