Summary

Google's Noto CJK (and other) fonts aren't rendered in a PowerPoint file in the viewppt macro. They will work in viewdoc and view-file.

This is a placeholder bug to track Aspose's bug PDFNEWNET-40221 which, although is for PDF and .NET, is the only thing we have for tracking this issue.

• http://www.aspose.com/community/forums/thread/656806/how-does-aspose-support-google-noto-font.aspx

Environment

• Google Noto Sans CJK SC Regular font from https://www.google.com/get/noto/ (for this example)

Steps to Reproduce

1. Add Google Noto Sans CJK SC Regular font via package management, or directly into a font folder
2. Update setenv.sh with (here for Ubuntu package)

   CATALINA_OPTS="-Dconfluence.document.conversion.fontpath=/usr/share/fonts/opentype/noto/ ${CATALINA_OPTS}"
   CATALINA_OPTS="-Dconfluence.document.conversion.slides.defaultfontname.asian=\"Noto Sans CJK SC Regular\" ${CATALINA_OPTS}"
   

3. Attach Google NOTO CJK Fonts don't display correctly in viewppt.ppt to a page
4. Add viewppt macro to a page with above PowerPoint file
5. Add view-file macro to a page with above PowerPoint file

Nothing appears in the log files.

Expected Results

The viewppt displays correctly. This image is what appears in PowerPoint. Note the lower g character.

Actual Results

The page renders as

Note that the left hand side font is incorrect and is likely pulling it in from another font, note the lower g character.

Notes

This isn't a bug directly in Confluence, but this is here to track the Aspose one.

Workaround

Use a different CJK font in the PowerPoint document or use the view-file macro.
