+Korean uses spaces between words, so you can generally prevent words from being split across lines by applying the CSS property `word-break: keep-all` to the paragraph, which should be much performant than installing BudouX.
+That said, we're happy to explore dedicated Korean language support if the above solution proves insufficient.
