Assuming that you are using TrueType fonts, the easiest way is to
parse the `kern' table manually.  Note, however, that modern OpenType
fonts no longer have a `kern' table.  Instead, kerns are stored in the
GPOS table, allowing two-dimensional kerning, context sensitive
kerning, and much more.  For the latter, the definition of a `kerning
pair' no longer exists.
