fcitx (Flexible Context-aware Input Tool with eXtension) is an input method framework for entering non-Latin characters. It supports Chinese, Japanese, Korean, and many other languages through various input method engines.
The framework provides a modular architecture with addons for different input methods like Pinyin, Wubi, Hangul, and Anthy. It integrates with desktop environments through GTK and Qt input modules.
fcitx handles input method switching, candidate selection, and provides a configurable user interface for text entry.
