Answer
When exporting to PDF from ANVL, some browsers can drop or distort special characters (Chinese, Japanese, Korean, etc.).
This isn’t an ANVL issue — it's caused by browser font/print settings.
Good news: it’s easy to fix.
In Chrome and Edge, turning on Background graphics in print settings can help. In Firefox, using the browser’s system print dialog can improve how fonts and characters are rendered.
Steps
Google Chrome
Open the workflow in ANVL.
Select Print.
Open More settings.
Turn on Background graphics.
Confirm Save as PDF or your preferred PDF destination.
Save or print again.
Microsoft Edge
Open the workflow in ANVL.
Select Print.
Open More settings.
Turn on Background graphics.
Save or print again.
Firefox
Open the workflow in ANVL.
Select Print.
Choose Print using the system dialog.
Save or print the PDF from the system dialog.
Additional Recommendations
If characters still fail, you may need to install a unicode font (e.g., Noto Sans CJK).
Download the Noto Sans CJK family from GitHub: notofonts/noto-cjk GitHub

Avoid browser extensions that modify print previews.
If the issue continues
Try a different browser.
Check whether the device has the needed language font installed.
If needed, contact your IT team for help with browser or font settings.
Additional Details
Browsers can handle fonts and print rendering differently, which can affect how special characters appear in exported PDFs.
Firefox supports printing through its own dialog and through the system print dialog.
If a required font is missing on the device, some characters may still not render correctly even after changing print settings. This is an inference based on how browser and system font rendering works.
