Hange Zoe isn't necessarily non-binary in the manga. In Isayama's words, Hange is whatever the reader interprets Hange to be, so therefore Hange can be male, female, or non-binary depending on who you ask. Kodansha has followed this rule in their official English translation by not giving Hange any pronouns at all, avoiding them entirely. However, this doesn't mean that non-binary pronouns are any more correct than male or female pronouns.

The wiki uses female pronouns on Hange's page and other pages where she appears because the anime designates her as female, which gives us more to work with than the complete lack of an official gender in the manga. Theoretically, all of Hange's pronouns could be removed entirely from all articles where the pronouns show up, but that's a huge and lengthy process that would only result in awkward sentence structure.
