Currently, TextExpander for iPhone & iPad supports these language keyboards:
TextExpander for iPhone and iPad supports native language, QWERTY, and AZERTY variants of several languages, see our article to learn more.
We expect to add more in future versions. Please feel free to let us know which language(s) and layout(s) are important to you. It is unlikely we will add support for complex keyboards such as Arabic, Chinese, or Japanese.
Instead, we offer support for custom keyboards in the TextExpander SDK. Feel free to tell your favorite keyboard developer all about it.
