Fcitx 5

Fcitx 5 is an input method framework for Linux, developed by The Fcitx Team. It provides the infrastructure that lets users enter text in languages and writing systems that need conversion, composition, or specialized keyboard handling. In a desktop session, it sits between the keyboard and applications, receiving keystrokes and producing the characters or candidate text selected by the user.

The software is relevant for Linux users who need more than direct keyboard input, such as language-specific input engines, candidate lists, or configurable typing behavior. It is a framework rather than a single dictionary or keyboard layout, so its practical use depends on the input methods and configuration installed with it. Fcitx 5 is released under the LGPL-2.1-or-later license.
