I think it is just name in SAO restricted to alphanumeric characters...although no prove that ALO can allow non-kana character, but if that's not ASCII then at least it should be Shift-JIS which included some kanji...and it use the : sign instead of writing like (Angel) as it'd normally be done when introducing one's species....
