    How do you note "aleph-null" ? Do you mean "aleph<sub>0</sub>" i.e.
    followed by a subscript zero? Where do you note the subscript (to the left
    or to the right?) I think it would go to the left per the linguistic aspect
    of hebrew letter aleph, but its use in mathematical notation may ignore the
    directionality and also note the indice as a subscript on the right;

    So the aleph there is not the Hebrew letter but a symbol... just like the
    other maths letters that are encoded. Now there's a good question: are the
    maths formulas directionaly oriented and do they follow the BiDi algorthm ?
    I hope they don't because it would become severely ambiguous (but they may
    contain pseudo-variables deonted as embedded substrings of text written in
    natural language; your "aleph" notation here does not qualify as it is used
    just as a symbol).

    Note that maths letters would also be good candidates as well for variants
    as superscripts/subscripts. This is endless!
