Apply the following extra requirements of Hungarian orthography
for sorting words and sentences:

– expand simplified double consonants;

– ignore spaces and hyphens;

– prefer lower case homonyms.

Note: automatic sorting is better this way, but it's still not error-free.

Important advantage, that now it's *possible* to fix all errors
in a semi-automatic way, using soft hyphens. Inserting them in bad
or ambiguous character positions will fix all automatic sortings later.

Example with consonant "gy", simplified form of long "gygy" is the
ambiguous "ggy" (it can be "g" and "gy", too, as in "meggyőz"):

= Bad =   = Now =   = Good (corrected, "|" signs soft hyphen) =
megbíz    megbíz    megbíz
meggyíz   megzavar  meg|győz
meggyőz   megye     megzavar
megzavar  meggyíz   megye
megye     meggyőz   meggyíz
megyünk   megyünk   megyünk
