I think that Xpdf does this on its own, 

        address@hidden:~/src/xpdf-3.01/xpdf$ grep 0x2019 *
        NameToUnicodeTable.h:  {0x2019, "quoteright"},
        PDFDocEncoding.cc:  0x2019, 0x201a, 0x2122, 0xfb01, 0xfb02, 0x0141, 
0x0152, 0x0160, // 90
        UnicodeMapTables.h:  { 0x2019, 0x2019, 0x27, 1 },
        UnicodeMapTables.h:  { 0x2019, 0x2019, 0x27, 1 },

as you can see, there is a mapping from 0x2019 to 0x27 defined in the
Xpdf source code.
