Use ToUnicode mapping even when unicode is 0.
CPDF_Font::UnicodeFromCharcode returns 0 only if ToUnicode map maps the charcode to 0. CPDF_SimpleFont::UnicodeFromCharcode and CPDF_CID_Font:: UnicodeFromCharCode return 0 only if the call to CPDF_Font returns 0. In other cases, these methods return an empty string. So when processing text, a 0 return from the method should not be replaced with the charcode. BUG=pdfium:583 Review-Url: https://codereview.chromium.org/2342073002
