Fcitx

Fcitx ([ˈfaɪtɪks], Chinese: 小企鹅输入法) stands for Flexible Context-aware Input Tool with eXtension support, is an input method framework with extension support for the X Window System that supports multiple input method engines including Pinyin transcription, table-based input methods (e.g. Wubi method), fcitx-chewing for Traditional Chinese, fcitx-keyboard for layout-based ones, fcitx-mozc for Japanese, and fcitx-hangul for Korean.

It supports UTF-8, GBK and GB 18030 character encodings, can run in Linux and FreeBSD, and supports XIM protocol, GTK (both 2 and 3) and Qt input method modules.

Before version 3.6, Fcitx used GBK encoding internally, which has been changed to UTF-8 in the 4.0 release. Since version 4.1, it has become highly modular, and has added support for Google Pinyin (which was ported from the Android version), fbterm, and KDE. The license was changed in the 5.0 release, from GPL to LGPL.
