Upper and lower case letters are treated the same, and underscores (_) are treated the same as spaces (consistent with how the Zulip UI handles emoji). ## Maximum file size The maximum file size for uploads can be configured by the administrator of the Zulip server by setting `MAX_EMOJI_FILE_SIZE` in the [server's settings][1]. `MAX_EMOJI_FILE_SIZE` defaults to 5MB.
