Rumi Numeral System Symbols: Additional characters proposed to Unicode

This is a proposal to encode a set of Rumi numeral symbols in the international character encoding standard Unicode. This set of characters was published in Unicode Standard version 5.2 in October 2009. Rumi, which is also known today as Fasi, is a numeric system used from the 10c to 17c across a wide area, spanning the area from Egypt, the Maghreb, to al-Andalus on the Iberian Peninsula. Rumi numeral symbols originate from the Coptic or Greek-Coptic tradition

Proposal for PENTAGRAM characters

This is a proposal to add 3 pentagram symbols to the international character encoding standard Unicode. These additions were published in Unicode Standard version 6.0 in October 2010

Proposal for Arabic Mathematical Alphabetic Symbols

This is a proposal to encode a set of characters used to write Arabic mathematical notation in the international character encoding standard Unicode. This set of characters was published in Unicode Standard version 6.1 in January 2012

Problem of Multiple Diacritics Design for Arabic Script

This study focuses on the design of multiple Arabic diacritical marks and to developing a model that generates the stacking of multiples Arabic diacritics in order to integrate it into a system of Arabic composition. The problem concerns the presence of multiple diacritics on a single basic letter. This model is based on the layering composition. The combination of diacritics with letters requires a basic layering to combine any diacritics in the word with their base letter, without having to deal individually and separately each pair of base letter and diacritics.Comment: 6 pages, 10 figure
