For one specific document (https://www.annualreports.com/HostedData/AnnualReportArchive/r/NYSE_REX_2020.pdf) some text in the viewer is missing:
There are some warnings in the console:
pdf.worker.js:117 Warning: TT: undefined function: 32 pdf.worker.js:117 Warning: cmap table has unsupported format: 2
I found pdf.js issue that looks the same as mine, but it was fixed a year ago: /Encoding prevents characters in a specific font from rendering but they do in ghostscript, chrome, and acrobat · Issue #14117 · mozilla/pdf.js · GitHub
It doesn’t look the same issue as Text Rendering Issues in Chrome and Edge, the solution proposed there does not fix this issue.
