[BUG] Non UTF-8 characters break PDF

[JeS24]

Problem Description

Non-UTF-8 characters such as μ are rendered fine in the web-preview, but not rendered in the PDF and cause artifacts as in the screenshot.

Expected Behavior

PDF should render properly.

Steps to Reproduce the Problem

1. Go to the website.
2. Select Microbiology from SBS.
3. Generate PDF.

Platform Details

• Browser (with Version): Tested on Edge Dev 98.0.1100.3 (Official build) dev (64-bit), Firefox 95.0.2 (64-bit)
• Operating System (with Version): Windows 10 Pro Build 19044.1415

Additional context

This is an issue with jsPDF unless we load a custom font. Since that will just bloat the website, let's not use non-UTF-8 characters in the database.
