I am working with someone who teaches an endangered language, of interest to a fairly small group. Many of the people in that group use only phones, and don’t have laptops. The language has a lot of special characters to represent the sounds of the language — that is, it has its own alphabet — but some of those characters are not available in any of the standard languages available by default on OSX.
- Is it possible to design a custom keyboard and define which keys will input which character?
- If so, is it possible to upload such a keyboard to the app store to make it available to people (he wants to make it free)?
