The latter may also be pronounced like their softened/palatalized equivalents before i, ě, ę and possibly before e. This pronunciation is not mandatory, though: they may as well be written and pronounced hard.
Soft consonants are normally represented by an acute or a haček, but other ways of writing are possible as well: nj, n’, etc. To avoid texts from becoming heavy on diacritics, it is recommended that before a vowel, soft consonants are written as a hard consonant followed by a j: nom. koń, gen. konja (instead of końa).
