[wenlzhang]

Although the word "optimisation" was included in dict_UK.txt, when checking with the following configuration, it still gives the following checking hint:

--output html --read-all
--dict dict_UK.txt
--remove IEEEeqnarray,IEEEeqnarray*
--check en_UK example.tex

I mark this as a duplicate of #142; the fix #143 resolves this issue as well as the other bug.
