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.
