Sorting is actually also tricky with dumb computers, because there is no way
for sort to know whether e.g. "nyolcszáz" contains a "cs" collating symbol
followed by "z" or a "c" followed by an "sz" collating symbol (the latter is
in fact the case).
cs+z would be sorted after "cz" (because "cs" comes after "c"), but c+sz
would be sorted _before_ "cz" because "sz" precedes "z".
I'd say this is unfixable. There is no way, short of understanding the
natural language, for a program to determine whether two (or three)
characters represent a single collating symbol or themselves.
Clearly, the Hungarian language must be fixed, either by introducing
separate glyphs for the composite "letters", or by no longer insisting that
something represented by more than one character is "a single letter". :)
