## CoqIDE
CoqIDE does not have support for unicode itself, but you can use the Intelligent
Input Bus (IBus) framework for multilingual input. First, install `ibus-m17n`
via your system's package manager. Next, create a file `~/.m17n.d/coq.min` to
configure an input method based on the math symbol list, and with some custom
aliases for symbols used a lot in Iris:

To use this input method, you should:
1. Enable it using the IBus configuration tool (there are different versions of
the configuration tool depending on the desktop you are using). The "Coq"
input method will typically appear in the category "other".
2. In CoqIDE, you can now use the input method by performing a right click,
and selecting "System (IBus)" under "input method".
