I thought I could just open the user dictionary:
C:\Users\unearthed\AppData\Roaming\Nemetschek\Vectorworks\2018\Plug-ins\Dictionaries\UserDictionary.txt
and add a whole list of words, but even Visual Studio Code will not recognise what must be a very non-standard .txt format, as each letter is padded with an unknown character.
So ... how do I add words to this thing, I'd like to dump about a 1000 in there (yes, I know this might slow it down but spelling mistakes are war crimes in my book).
