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:
