The responsibility for handling Latex special characters belongs to the programmer, rather than Octave.  "help print" for -pdflatex says.

The text that is written to
the LaTeX file contains the strings *exactly* as they
were specified in the plot.  If any special characters of
the TeX mode interpreter were used, the file must be
edited before LaTeX processing.  Specifically, the
special characters must be enclosed with dollar signs
('$ ... $'), and other characters that are recognized by
LaTeX may also need editing (e.g., braces).

It might be possible to write some sort of script, in Octave or in a more text-oriented language like Perl, that uses regular expressions to automatically protect special characters.

This seems like a feature request.

to reproduce:

a=[1 2];
pie(a);
print("test", "-dpdflatex");

results in a test.tex that cant be compiled by pdflatex. The reason ist, that the pie chart does not escape the % sign, when the labels on pie chart are constructing automatically
