The QPDF_String::getUTF8Val() method was not treating strings that
weren't explicitly Unicode as PDF Doc Encoded. This only affects
characters in the range 0x80 through 0xa0.
This tokenizes outer parts of the file, page content streams, and
object streams. It is for exercising the tokenizer in isolation and is
being introduced before reworking the lexical layer of qpdf.
Make sure to link from the source tree before linking from the system.
In many environments, this is necessary to allow a newly built qpdf to
link properly instead of trying to link or resolve libraries from an
older installed version.
