LibreOffice released Emoji and in-word replacement support since 5.0 version. For example, in traditional Chinese we translate "registered" string wich is ® (U+000AE) in extras/source/autocorr/emoji.po as "註冊商標". It is expected AutoCorrect can replace the text of :註冊商標: in Chinese (traditional) locale to ® emoji symbol. However, AutoCorrect does not work for traditional Chinese in this case. Reproduce steps: 1. Type or cut and paste :註冊商標: to Writer 2. press Enter to expect AutoCorrect to work and replace :註冊商標: to ® Result: Nothing happened. :註冊商標: is still :註冊商標: Reproducibple: Always Expected Result: :註冊商標: should be replaced with ® like :registered: does.
