Not having the same sequence of bytes is painful. There is a reason we
aimed for that with MULE when possible (some Japanese coding systems
don't make it possible) and with utf-8.
However, that is utterly orthogonal to the question how to work with
specially displayed/generated material like mode lines, group summaries,
help texts and so on.
For example, Emacs has a somewhat quaint mechanism called "fields". It
would not make much sense to let directionality bleed over field borders
into neighbouring neutral characters, effectively moving them visually
across the field.
