MacOS: ABC Extended Keyboard Further Extended
A poster in the Apple Support Communities (ASC) has pointed out that Apple's ABC Extended keyboard layout lacks the ability to produced chracters with the diaeresis below diacritic. This is useful for certain romanization systems for the Arabic script used in a wide range of languages. A custom ABC Extended layout which includes Combining Diaeresis Below at Option-Shift R is available here.
