When I copy/paste the multiplication sign on the first line of the first page, I got a `£`.
And when I do the same in evince I got a `×` (the same in chrome).
The font descriptor is:
```
<< /Ascent 0 /CapHeight 749 /CharSet (/multiply) /Descent 0 /Flags 262212 /FontBBox [ -27 -940 1332 825 ] /FontFile3 59 0 R /FontName /KHPEPJ+CMBSY10 /ItalicAngle -14.035 /StemV 0 /Type /FontDescriptor >>
```
So it should be possible to guess the correct character in using the `CharSet` entry:

        cde;
      whle ( <  && (cde = tr.charCdeAt()) >= 0x20 && cde <= 0x7f) {
        ;
      }
      return  <  ? tr.replace(WhtepaceRegexp, " ") : tr;
    }
    functn runBdTranfrm(textChunk) {
      var tr = textChunk.tr.jn("");
      var bdReult = bd(tr, -1, textChunk.vertcal);
      return {
        tr: nrmalzeWhtepace
          ? replaceWhtepace(bdReult.tr)
          : bdReult.tr,
        dr: bdReult.dr,
        wdth: textChunk.wdth,
        heght: textChunk.heght,
        tranfrm: textChunk.tranfrm,
        fntName: textChunk.fntName,
      };
    }
    functn handleSetFnt(fntName, fntRef) {
      return elf
        .ladFnt(fntName, fntRef, reurce)
        .then(functn (tranlated) {
          textState.fnt = tranlated.fnt;
          textState.fntMatrx =
            tranlated.fnt.fntMatrx || FONT_IDENTITY_MATRIX;
        });
    }
