Most examples in this guide deal with texts in English. If you want to handle texts in Chinese or some other language, you need to choose the language in the main Controller.
If in the drop-down list
the language you need isn't available, click Edit Languages and choose the language you want:
and drag it to the right or click the button in the middle.
You'll see an option to select that language as your "main language" (with which WordSmith will start up by default), or else just as an available language.
In this screenshot, English has been selected and some suitable choices for English have been made such as apostrophes allowed within a word, hyphens separating forms like self-conscious into two words and showing that Arial 10 is the default font, etc.
Finally, save your settings.
