Base 64 is the encoding used in the data: URL scheme. What is missing
(and invalid, because otherwise text/plain is assumed) is the MIME type
of the resource. But in fact it is a CEF format font. CEF is an Adobe
subset of OpenType - using truetype tables, but only allowing glyphs in
Type1 format not Truetype format.

For two reasons One, it supports the @font-face block Two, it supports
the particular font format that is used.

I wqish Batik error messages would distinguish between "invalid' and 'as
yet unsupported'.
There is no error in the document, apart fromthe lack of a mime type in
the url

That doesn't mean they are embeding the fonts, it might mean that they
are referencing local TrueType fonts 9and the blockiness might be from
the Freetype rasterizer, which by default compiles with
US-software-patent-avoidance set to "yes" ;-)
