For one specific document ([https://www.annualreports.com/HostedData/AnnualReportArchive/r/NYSE\_REX\_2020.pdf](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:

```javascript
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](https://github.com/mozilla/pdf.js/issues/14117)

It doesn’t look the same issue as [Text Rendering Issues in Chrome and Edge](https://pdfjs.community/t/text-rendering-issues-in-chrome-and-edge/2185), the solution proposed there does not fix this issue.

My version is:

```javascript
Build: "MS8yMC8yMDIzfGIzYTExOTI2Yw=="
Core version: "8.7.1"
Full API: false
UI version: "8.7.0"
WebViewer Server: false
webviewer.min.js: "8.7.1"

```

@polina.meleca  
I had created same bug report some time ago, and actually this issue was fixed in newer versions of pdfjs-express (on my project we currently use “@pdftron/pdfjs-express”: “^8.7.4”), so you can try to update the library version, maybe it would help.
