I'm trying to move a script from invoking lots of sed and awk to bash

Is there a tr equivalent to the following?

You realize that tr is not a Bash builtin, right?
No, I didn't check, actually, thanks for pointing that out. The tr
command is probably easier for some of the younger folks who will have
to read this later on[1]. Now I'm curious and might run some tests on
the two versions and see which is quicker -- though that's totally not
the point with scripting (well, isn't supposed to be, anyway).

1. Rantesque continuation:
...as they seem so allergic to learning one or two sed commands that
they will instead implement a parse/convert library from scratch in
their favorite vanity language complete with intermediate working files
and locks... and viola, new dependencies, attack vectors, opportunities
for frozen jobs, etc are born.
I'm exagerrating, of course, but sadly not by much. In my current
situation its far more likely that someone will look up and understand a
command from coreutils than a spot of sed or my larger blobs of awk. I'm
finding, to my chagrin, that what is easy and straightforward to me is
clearly not easy and straightforward to the younger folks who came along
after the Marketing Department decided that "all networking, ever" was
synonomous with "web", and "all UIs, ever" were synonomous with "browser".
