Richard Ishida has created a chart to show which features (for example, combining characters, ligatures, case, baseline etc.) apply to a number of writing systems, including English, French, Hausa, Igbo, Indonesian, Portuguese, Spanish, Swahili, Vietnamese and Yoruba written with the Latin script. The characteristics described are based on the exemplar character lists in the CLDR. The chart is intended to give a basic idea of which writing systems require what types of feature support.
