Behavior:
Some characters from some fonts display as an error character.bad-character-display.jpg (101.3 KB)
Expected:
Ideally display all characters as written. If the engine cannot handle a font, perhaps fall back on some default font.
Thank you for reporting this issue. Can you please share the source file and which version of GropuDocs.Viewer you’re using?
The source file is a PPT file and i can’t upload it and when zipping it i get a message saying it’s too big. I’ll try replying back to your email. We are using GroupDocs.Viewer.UI version 6.0.13 and GroupDocs.Viewer.UI.SelfHost.Api version 6.0.15
You can reproduce the bug from your demo website: View PowerPoint files online | Free GroupDocs Apps

Thank you for attaching the source file. Such an issue may happen if there are no required font(s) installed. In this case, the font is being replaced with another one. As a result, we can see incorrect output. There are two solutions here:
- Install the required fonts into your system.
- Specify a folder with the additional fonts.
Install the required fonts into your system
In this case, we need SourceSansPro font that is available for download on the Internet.
If you’re running the app on Windows you can install fonts manually or using Windows shell script
When running on Linux you can copy the fonts and build fonts cache. As en example, the following instructions from Dockerfile that I’m using will do the job:
# copy additional fonts and update cache
COPY ./Fonts /usr/local/share/fonts
RUN fc-cache -f -v
The complete sample application with Dockerfile - viewer-net-ui-with-additional-fonts.zip.
Specify a folder with the additional fonts
In case you don’t want to install fonts you can set a folder(s) with fonts in Program.cs file.
using GroupDocs.Viewer.Fonts;
using SearchOption = GroupDocs.Viewer.Fonts.SearchOption;
//...
FontSettings.SetFontSources(
new FolderFontSource("./Fonts", SearchOption.AllFolders));
One more code example can be found in Set custom fonts topic.
After making additional tests, I found that fonts are not correctly loaded when rendering files to PNG and JPEG but work well when rendering to HTML and PDF. We’ll update you when this issue is fixed. The issue ID in our internal bug tracker is VIEWERNET-4434.

Let me check the current status with the development team.
Due to our Free support policies we can provide support on this forum in the text format. I’m sorry for the inconvenience.
If you need support on a priority basis, along with direct access to our Paid Support management team you can obtain Paid Support Helpdesk.
I’ve got the update from our development team. The fonts-related issue has been planned for the investigation. We may expect the results by the end of the next week. When we have any new updates we’ll notify you.
Hi Vladamir,
Has there been any progress on this one?
I’m sorry for the delayed response. This issue was postponed for some time. We expect to have the estimations for this issue at the beginning of the next week.
We’ve got the update from the development team. The issue was fixed but the fix did not pass code review. When we have any new information we’ll let you know.
The fix has passed the code review stage. We plan to include it in GroupDocs.Viewer for .NET 24.1 the next month’s release.
