Japanese Gnomish

So I'm dumb because I didn't realize that the Gnomish in the Japanese Artemis Fowl books would probably be written in all three Japanese writing styles...how the heck does anyone figure that much out even if Japanese is their first language?????

Also gonna practice my Japanese today soooo...いきますよ！

僕は日本のアルテミスファウルの書籍ノーム語すべて3日本の書体で書かれることを認識していなかったので、だから僕はばかなんだ。日本人が母国語であっても、誰もがそれほど出方法一体を把握しますか？？？？

But seriously, if anyone knows how to read Gnomish in the Japanese books please help me! I learned it in English but not in Japanese >.<
