[modesty]

The first line of text in the sample PDF uses type 3 font and custom encoding, which is not supported at this point, same as issue #363. Two options to move forward:

1. submit PR to support type 3 font rendering in canvas.js
2. recreate the PDF with standard TrueType font and standard encoding

PR https://github.com/modesty/pdf2json/pull/401 adds supports for type3 glyph font support, should be fixed
