Getting rid of a weird character

I'm working on some Japanese text that has been transliterated into English. What I
received has a chracter that looks like a hyphen with a downward stroke at the end. I
believe it is a non-printing character. I can find it in my character map and insert one,
but I cannot copy and paste it into the find/replace box. I want to delete all these
characters. I believe they represent an accent mark, which is not needed in Japanese
Romanji.

Perhaps the hyphen with the downward stroke at the end is used to represent some kind of a
non-printing chracter. Like the pilcrow, I can keyboard it in. Like the pilcrow, I
cannot do a find/replace. There must be a way!

I'm using Word XP.
