when typing "rkk" with WuBi IME in scim (which is supposed to be the character 操), the character "肏" (which means "fuck" and sounds the same as 操 in Chinese, however in glyph-based WuBi IME the input code is completely diffferent) will appear in the 2nd candidate. Removing such characters would be more appropriate
Tz-Huan, can you please have a look?
