Fix CPDF_CIDFont::GlyphFromCharCode for fonts flagged with PDFFONT_SYMBOLIC
UnicodeFromCharCode should be tried even if the font is flagged as
PDFFONT_SYMBOLIC. The result should be checked in case it's empty. This
fixes some corpus tests that were being incorrectly rendered, as well as
the bug below.
A deps change will be required before landing this CL.
