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:

          length: suggestedLength,
        };
      }
    }
    warn('Invalid "Length1" property in Type1 font -- trying to recover.');
    stream.pos = streamStartPos; 
    var SCAN_BLOCK_LENGTH = 2048;
    var actualLength;
    while (true) {
      var scanBytes = stream.peekBytes(SCAN_BLOCK_LENGTH);
      block = findBlock(scanBytes, EEXEC_SIGNATURE, 0);
      if (block.length === 0) {
        break;
      }
      stream.pos += block.length; 
      if (block.found) {
        actualLength = stream.pos - streamStartPos;
        break;
      }
    }
    stream.pos = streamStartPos; 
    if (actualLength) {
      return {
        stream: new Stream(stream.getBytes(actualLength)),
        length: actualLength,
