In the 1972 spelling reform that unified Indonesian and Malaysian spelling conventions ("Ejaan yang Disempurnakan", regulated by MABBIM), it was agreed to use neither diacritic. There is no longer an orthographic distinction between and ; both are spelled with an unmarked . For example, the word for 'wheeled vehicle' in Indonesia and Malaysia, which was formerly spelled in Indonesia and in Malaysia, is now spelled in both countries. This means that the pronunciation of any given letter in both Indonesian and Malaysian variants is not immediately obvious to the learner and must be learned separately. However, in a number of Indonesian dictionaries and lesson books for foreign learners, the notation is preserved to help learners.
