You mentioned yet another issue in Einstein's paper:

it was not easy to decide, to which alphabet certain characters belong.

E.g. 'P' could be a large Latin 'p' or a large Greek 'Roh'.

other ambiguities:

small italic Latin 'v' and Greek 'ypsilon' are hard to distinguish
and
small italic Latin 'a' and small Greek 'alpha' are practially 
undistinguishable.

It requried a strong lens and some knowledge in criminalism to identify 
the meant alphabet.

Since Einstein didn't define any variable properly, you had to guess.
