Every wanted to find just the right ampersand? Or question mark? Checking it against every font in your system manually would be a pain. Font Book doesn't have the font sampler feature you need to do this.
But the problem can be solved with ... AppleScript:
tell application "TextEdit"
make new document at the end of documents of it
set paraIndex to 1
tell application "Font Book"
set allFaces to get every typeface
repeat with t in allFaces
set currentFace to PostScript name of t
set currentName to displayed name of t
tell the front document of application "TextEdit"
set size to 18
set paragraph paraIndex to "? (" & currentName & ")" & return
set font of character 1 of paragraph paraIndex to currentFace
set paraIndex to paraIndex + 1
