Please check GfxCIDFont::getNextChar in GfxFont.cc, for non 8bit string,
you may find how poppler translates a bytestream to Unicode string.
I have to note that the text in PDF is related with a font in PDF,
so encoding info is determined by the font.

Also please check poppler-data package for the mapping table resource.
