最近在使用CentOS7 桌面版本，在用五笔打字时，有些字打不出来，比如“覆盖”。但是在WIN下能打出来。
从网上查找原因，原来是需要改成GBK字符集。方法如下：
修改文件 vim /usr/share/ibus-table/engine/table.py 定位到227行
# self._chinese_mode: the candidate filter mode, # 0 means to show simplified Chinese only # 1 means to show traditional Chinese only # 2 means to show all characters but show simplified Chinese first 表示所有汉字，但首先显示简体中文。 # 3 means to show all characters but show traditional Chinese first # 4 means to show all characters # we use LC_CTYPE or LANG to determine which one to use
把下面这三行注释
＃self._chinese_mode = variant_to_value(self._config.get_value( ＃self._config_section, ＃"ChineseMode"))
添加一行：
self._chinese_mode = 2
然后重启输入法。
附：安装五笔
yum list |grep wubi ibus-table-chinese-wubi-jidian.noarch 1.4.6-3.el7 ibus-table-chinese-wubi-haifeng.noarch 1.4.6-3.el7
yum install ibus-table-chinese-wubi-haifeng.noarch -y
