I think it's γγΈγ‘γγγͺγ, actually (see http://www.nicovideo.jp/watch/sm1274898). Also, γͺγγ¨γγγγ¨γ§γγγ (and variants, such as γͺγγ¦γγ¨γ ) does not express uncertainty about the nature of something, but horror and negative surprise. I'm not sure if there's an English equivalent that is close to the letter, but the meaning is something like "That's terrible!"
