Yogh

I am looking for fonts that contain the Old English character yogh for a private project. I have so far found it in Minion Pro and Garamond Premier Pro (and Times New Roman, but we won't mention that). Can anyone tell me if there is a quick and easy way of identifying fonts that contain a specific glyph like this. At present I'm opening every single font on my system and searching for it, but it's taking for ever.

If it's relevant, I'm on Windows Vista.

Many thanks for you help,

John
