We show that developing universal, up-to-date, high-coverage and high-generalization hyphenation patterns is feasible, generated from semi-automatically prepared word lists from actual language usage. We evaluate the new approach and argue that the new Czechoslovak hyphenation patterns bring significant coverage and generalization improvements, and space savings. We share all the data, word lists, and workflow for reproducibility and usage.
