Lontara Bilang-bilang is a cipher of the Lontara script, currently used for Buginese poetry. This script uses the Eastern Arabic numerals-inspired letterform to substitute the Lontara script, as a way to hide it to the Dutch at the time. It was an adaptation to a similar ciphers of the Arabic script that has been used in South Asia around the 19th century.
Usage In Buginese literature, Lontara Bilang-bilang is sometimes used as a substitute to Lontara script in writing basa to bakke', a play-on-words, as well as élong maliung bettuanna, poetry with some hidden meaning using basa to bakke'. In this script, each base letter in standard Lontara are substituted with forms derived from Arabic script and its numerals, with standard, unchanged Lontara vowel diacritics attached to them.
Cipher system Lontara Bilang-Bilang substitutes Arabic letters with stylized numerals in accordance with Abjad numerals, a system that has been used in 19 AD in what is now Pakistan and Afghanistan. In Bilang-Bilang, many letters for Arabic sounds not in Buginese are not used, while for sounds existing in Buginese and Malay, new letters are added with more stylization. For example, ب have a numeral value of 2 and therefore is substituted by a stylized form of ٢, illustrated as follows: ArabicValue LontaraBilang-bilang Lontara Latin Commentsب٢2ᨅbaStylization of ٢ with a short vertical lineك٢٠20ᨀkaStylization of ٢ with a medium vertical lineر٢٠٠200ᨑraStylization of ٢ with a long vertical line Jawi letters for Malay and Buginese sounds are formed with dots as equivalent for its Arabic counterpart.
