PreussType PRO and PLUS Fonts cover a huge number of Unicode characters. You will see a range of them here.
Having the information that characters are encoded in certain environments of language you cannot transfer the use of these encodings for certain languages or special setting applications. As soon as a letter is used in a Unicode environment the whole environment is indicated as permanently existing. Please find the list of languages where you can easily insert PreussType PRO and PLUS Fonts, here on this website.
PreussType takes care to offer you languages which can meet your high requirements. If there are certain symbols or whole code spreadsheets for your database applications missing, we will develop these to fit your needs.
