you probably mean latex (macro package) here as luatex (engine) itself
doesn't do anything
keep in mind that context implements much of math in a complete
different way, so solutions for problems or wishes are done differently
too; in this case we try to use unicode and some lua magic instead of
character juggling at the tex end
we also need to keep in mind that characters have to behave well in
tagged pdf and exports and so
