MacOS has an input method known as "ABC - Extended", which allows inputting most diacritics with any Latin letters. With it, "Alt" + various keys give a diacritic waiting to be composed, and pressing a letter produces the letter with the specified diacritic. For example:

Alt + E gives acute (´), which can be used to produce é or ń

Alt + U gives diaeresis (¨), which can be used to produce ü or ÿ

Alt + C gives cedilla (¸), which can be used to produce ş or ķ

Alt + B and Alt + V give breve (˘) and caron/háček (ˇ) respectively, which can be used to produce Romanian ă and Pinyin ǎ.

My question: is there a similar way to input various diacritics on iOS/iPadOS? All of the system keyboards seem just to offer a limited set of accented letters.



The best way to have full coverage of diacritics is to get a hardware keyboard to go with the iOS device. Then you can just choose ABC Extended as your mapping.

Otherwise you have to search for a 3rd party keyboard (check the Keyman app) or use an app like Unicode Pad.

    THANK YOU. I don't mind using a third-party keyboard at all; that was kind of what I was expecting having to do. But I seriously have no idea how I never noticed you could map hardware keyboard inputs under General - Keyboard - Hardware. Silly of me to have assumed that iOS must of course automatically take care of that for me. It's fantastic not having to choose between hardware/software keyboard and diacritics. Many thanks again! (I've also never realised SIL stood for "Summer Institute of Linguistics" for some reason...kudos to SIL anyway 😛) – Rethliopuks Nov 6 '19 at 15:06

In iOS holding the letter down will present a choice of diacritics.

  • Are Cedilla and Breve there ? – anki Nov 6 '19 at 14:00
  • Lots of stuff cannot be made this way. Like it says in the question already "All of the system keyboards seem just to offer a limited set of accented letters." – Tom Gewecke Nov 6 '19 at 14:51
  • Cedilla is available for most but Breve does appear to be missing. It is easy to add a language specific keyboard in iOS. Or as the accepted answer states, use a third-party keyboard. – Dave Nelson Nov 6 '19 at 18:11
