TeX and its successors, including the initial version of Omega, all suffer from the same technical limitations such as non-adequate support for TrueType/OpenType font formats or the lack of distinction between character and glyph data. In this paper, the authors present Omega2 that provides extensibility through both external modules and the texteme concept that supersedes TeX's tokens and nodes as well as characters and glyphs. Omega2's modules, while much more powerful than macros or OTPs, provide relatively easy access to Omega2's internals without need to touch the source code itself. Among immediate applications are full OpenType support (GSUB, GPOS, etc.), use of independent linguistic tools such as hyphenation algorithms, or support for Unicode's Bidirectional Algorithm.
