Arabic letter frequency

rdf:langString Arabic letter frequency

rdf:langString The frequency of letters in text has often been studied for use in cryptanalysis, and frequency analysis in particular. No language has an exact letter frequency distribution, as all writers write slightly differently. As a rule texts in different languages using the Arabic script (e.g. Arabic, Ottoman Turkish, Persian and Urdu) will have different letter frequencies, most obviously in the case of letters which are only used in some languages (e.g. the Persian letters پ, چ, گ, which are not used to write in Arabic). Methods encoding the most frequent letters with the shortest symbols were pioneered by telegraph codes, and are used in modern data-compression techniques such as Huffman coding.
