They are not in general available in PDF, the language. The
cairo-based device embed individual glyph information from such fonts
(perhaps as vectors and perhaps as bitmaps).

But you would still need to make the font available to your PDF
viewer/printer, and in general that does need coversion (to a font
type supported in PDF or to bitmaps/vectors).

Have you not considered the built-in and fully featured cairo_pdf
device? (Not Windows, but you didn't tell us your OS.)
