Languages written with variants of the Latin alphabet or completely different character sets require teaching how to read and write these. Where stroke order is important or useful, provide images describing these. There might already be some available on Commons:, such as at the Commons Stroke Order Project or Commons:Tamil alphabet.
Audio and video clips to illustrate conversations by native speakers are useful. You can direct readers to popular media in the language you are teaching for practice to keep learners interested and help them immerse themselves in the language.
