2017-07-19Use CFX_WideString in CPDF_NameTree functions to strip BOMchromium/3162Jane Liu
PDFium doesn't strip BOMs during parsing, but we should strip BOMs when retrieving parsed strings in CPDF_NameTree to ensure consistency and appropriate function behavior. See the bug for more info. As outlined in Bug=pdfium:593, the solution is to call GetUnicodeText() instead of GetString(). I added a GetUnicodeTextAt() function in CPDF_Array, which is symmetrical to GetUnicodeTextFor() in CPDF_Dictionary. I then changed the input variable types to CPDF_NameTree functions to be CFX_WideString instead of CFX_ByteString, and modified all the calls to them. I also added a unit test for nametree, which would fail prior to this change. Nametrees with non-unicode names are already tested by embedder tests.

2017-07-13fix skiapaths for sparse type1 on macCary Clark
PDFium's native code reverse engineers the glyph code on Mac by taking the character code point, looking up its name in FreeType, and then finding the named glyph's index from CoreGraphics. If the FreeType glyph index and the CoreGraphics index don't match, it uses CoreGraphics' index when drawing. The IDs match except when drawing an embedded Type 1 font tha has been sparsely populated to cut down on the PDF size.
