The Romanisation of Bengali is the representation of the Bengali language in the Latin script. There are various ways of Romanisation systems of Bengali created in recent years which have failed to represent the true Bengali phonetic sound. While different standards for romanisation have been proposed for Bengali, these have not been adopted with the degree of uniformity seen in languages such as Japanese or Sanskrit. The Bengali script has often been included with the group of Indic scripts for romanisation where the true phonetic value of Bengali is never represented. Some of them are the "International Alphabet of Sanskrit Transliteration" or IAST system (based on diacritics), "Indian languages Transliteration" or ITRANS (uses upper case alphabets suited for ASCII keyboards), and the National Library at Calcutta romanisation.
