This implementation is based on the same feature I added to Serenity's TextEditor: https://github.com/SerenityOS/serenity/pull/17477 (cherry picked from commit ecf2cc600bea8f8396061f5fe6aba8358a033bbb; amended to change Unicode::Segmenter to Locale::Segmenter due to LibLocale and LibUnicode being separate libraries in serenity)
