log2vis is NOT a good approximation of vis2log for "impossible" visual
strings like "CBA 123 xyz" (where "CBA" represents Hebrew letters).

Indeed, but on most cases, log2vis is a quite-good approximation to
vis2log. IIRC I once used this fact for some real, simple, dataset,
and the results were just fine. Do note that vis2log is not a function,
in the mathematical sense - there are cases of two different "logical"
strings that log2vis maps to the same "visual" string. So a potential
vis2log would have to either make a guess or return all possible
results, or some other such kludge. In reality, if you kept important
data in visual form, you might have a problem, and need to manually fix
things, after running some approximation (such as log2vis).
