Bit arithmetic on Unicode characters?

Other than converting between UTFs, is bit arithmetic commonly performed on
Unicode characters? I was under the impression that it's a rarity if it is
done at all.

I've been working on a proposal for additional chess symbols used in chess
problems and variant games, and I've been in communication with the World
Federation for Chess Composition, which is the international organization
in charge of chess problems. We have agreement on the repertoire and the
text of the proposal, but the arrangement of the proposed characters within
the new block is a sticking point. Some representatives of the WFCC have
proposed alternate arrangements that assume there will be a need for
bitwise operations to covert between the existing chess symbols in the
Miscellaneous Symbols block and related symbols in the new block. I don't
see the need but maybe I'm missing something.
