Support of Other Countries
OS/2 2.1 was localized into a relatively small set of languages, but supported a much wider set of languages and countries with the appropriate country, codepage, and keyboard settings. Such indirectly supported languages included Turkish, Polish, Czech, Hungarian, or Icelandic.
takze asi si to pamatuju spatne a pouzivali sme jen moznost ceskych znaku a klavesnice :-)
jinak OS/2 4 Merlin modernizovane (nejen) GUI melo dost a mnohem lepsi nez tehdy Windows 9x/NT ;-)
