Reversing a file line-wise and character-wise

Input:

hello
enrico

output:

ocirne
olleh

To do this, I can simply tac a file and pipe the output to rev (or the other way around), so one function that does the job is just this:

revtac() { tac "$@" | rev; }

Is there a built-in function for the job? I suspect that this could potentially break something, as it would reverse ` and ` on Windows-generated files, but I'm still interested.
