Anyway, in spite of not being open source and not supporting any open formats, WPS can read and save .doc and .docx files in a way that works together with MS Office, and since it runs natively on linux it's a practical solution until the day libre/openoffice become viable alternatives.
There doesn't seem to be any simple way of changing language beyond replacing the default dictionary files. It ain't pretty, but it works.
In my case I wanted Australian English, so I first installed the myspell dictionary:
sudo apt-get install myspell-en-au mkdir ~/.dictionaries sudo mv /opt/kingsoft/wps-office/office6/dicts/main.aff /opt/kingsoft/wps-office/office6/dicts/en_us.aff sudo mv /opt/kingsoft/wps-office/office6/dicts/main.dic /opt/kingsoft/wps-office/office6/dicts/en_us.dic sudo cp /usr/share/hunspell/en_AU.dic /opt/kingsoft/wps-office/office6/dicts/main.dic sudo cp /usr/share/hunspell/en_AU.aff /opt/kingsoft/wps-office/office6/dicts/main.aff
Start WPS and it should now speak 'Strine.
