Characters Missing or Replaced When Exporting Canned Reports

Technical queries
#1

Hi Helical Insight team,

I encountered an issue while exporting a Canned Report. The problem occurs in both the Docker deployment and the JAR-based installation of Helical Insight.

The export results are as follows:

  • PDF: Chinese characters are not displayed.
  • JPG/PNG: Chinese characters are replaced with empty squares.
  • Word/XLS/TXT: Chinese characters are displayed correctly.

I checked both the application logs and the browser console, but no errors were reported.

Could you please help investigate this issue and advise whether any configuration are required?

Thank you.

Hi @jingxiang ,

When we export, there are limited font types which are present by default which are used. If any custom font, which is not directly present in that, is used though it appears on the HTML page, it does not appear in the PDF (and few other exports). It uses often fall back font or shows special character.

If you can share the font download link, we can compile the font from our end and give you a file which you can deploy at your end. Then when exporting happens, even that specific font will also appear properly in the export.
