Getting information about fonts used in a document
The Font Information dialog box lists the original font used in the original
document, font type, font encoding, and the font used in Reader to display the
original font. Only the fonts encountered in the document so far are listed. To
see a list of all fonts used in the entire document, click the List All Fonts button.
You can use the Font Information dialog box to see what fonts were used in the
original document and whether the same fonts are being used as you view it. If
substitute fonts are being used and you aren't satisfied with their appearance,
you may want to install the original fonts on your system or ask the document
creator to recreate the document with the original fonts embedded in it.
While Acrobat Reader creates a substitute font in Mac OS, the pointer appears
as a spinning letter a.
