How illiteracy is treated in fiction.
Illiteracy is treated very differently depending on the languages of the work in question. In the Western world, a character being unable to read is a minor tragedy, and a sign that someone seriously screwed up raising them. Often, that character's plot will revolve around learning to read. In the east, however, this is not quite the case. In Japan (and a number of other countries), it isn't all that surprising to find someone who can't read kanji, or whatever the local high-level equivalent is. Kanji is so advanced that even people who study the Japanese language regularly are expected to need a dictionary on hand to read literature. This has spawned an entire media type, the Light Novel, which mostly uses the simpler hiragana instead. Therefore, a Japanese character who can't read/write kanji is treated as a bit of an idiot, but nothing to write home about. Foreign characters also fall into this a lot.
