Gives TypeError on Russian letters

[SeanLangre]

Code:

var Filter = require("bad-words");
var badWordFilter = new Filter();

var badwordtest = "мило"
var teststring = badWordFilter.clean(badwordtest);

Error:
Uncaught TypeError TypeError: Cannot read properties of null (reading '0')
at clean (..node_modules\bad-words\lib\badwords.js:58:41)

Need to modify splitRegex prop. By default /\b/ defined as splitter.
To support russian language need to set "/\b/gu". But it still not working with a single world, like "Привет"
