So, it would work even if I would add "\999999999", because Emacs
would not recognize and simply ignore it, which means the only reason
it worked was explicitly set encoding (iso-8859-2)?

As base, but before ispell.el sends the string to the Aspell it
translates it to uft-8, right?  Because that's the only difference
between my custom "pl" dictionary and value of "polish" in
ispell-dictionary-alist.

So, with my setup (not saying that it's the best one, it's just
current one, if there is a better one I can change), for Polish lang,
I have to define local dictionary with iso-8859-2 coding?

If it's a problem of MinGW, and my setup, then I guess it's not an
Emacs problem, so yes, it can be closed.
