The paper presents development of complex OpenType fonts.The sample fonts cover Czech and Georgian handwriting with numerous letter connections.At the beginning, general principles of "advanced typography" are showncomplex metric data represented by OpenType tables (GSUB and GPOS) -and compared them with the ligature and kerning tables in METAFONT.Then the history of the OpenType font production is described -approaches, tools and techniques.Crucial problems, critical barriers, attempts and ways how to reach successful solutions, are discussed and several tools for font creating, testing, debugging and conversions between various text and binary formats are demonstrated.Among these tools are, for example, AFDKO, VOLT, FontForge, TTX, Font-TTF.Their features, advantages, disadvantages, and also cases of possible incompatibilities (or maybe errors) are illustrated.Finally, using the OpenType fonts in the T E X world applications are presented: X E T E X and LuaT E X (ConT E Xt MkIV), the programs allowing to read and process OpenType fonts directly.
