Glyph mapping corruption when exporting Aptos font to PPTX ("9" becomes "G", "&" becomes "C")

When exporting a presentation from Adobe Express to the Microsoft PowerPoint (.pptx) format, specific characters utilizing the Aptos font family are experiencing severe glyph mapping corruption.

Specifically, the number "9" is consistently converting to the uppercase letter "G", and the ampersand symbol "&" is converting to the uppercase letter "C" in the final exported file.

The text renders perfectly within the Adobe Express web canvas. The corruption only occurs during the export process and is immediately visible when opening the resulting .pptx file in Microsoft PowerPoint.

This is an encoding/mapping issue, not a localized styling glitch, as it persists across the entire Aptos font family. I have tested and confirmed that the error occurs regardless of the font weight (Regular, Bold, Light) or the point size being used.

      Hi ​@interesting_creator00b1,

       

      Thanks for reporting this issue. I'm sorry you're experiencing problems when exporting your presentation to PowerPoint.

      It sounds like certain characters in the Aptos font family are being incorrectly mapped during the PPTX export process, where characters such as "9" and "&" are replaced with different letters in the exported file, even though they display correctly within Adobe Express.

      To help us investigate further, could you please share:

      • A sample PPTX file showing the issue?
      • Whether the problem occurs with all presentations or only specific projects?
      • If the issue persists when using a different font family?
      • Your browser and operating system details?
      • A screenshot showing the text in Adobe Express compared to the exported PowerPoint file?

      As a temporary workaround, you may want to test exporting with an alternative font to see if the character substitution is specific to Aptos.

       

      Regards,

      Tarun

      Differences between PDF export and PPTX export

      Hi Tarun,

      Thank you for acknowledging this issue. I’m glad to finally have someone looking into the export engine, as Tier 1 support recently closed my ticket claiming this was a Microsoft issue, which is factually incorrect since Adobe Express is the tool generating the corrupted .pptx file.

      To address your workaround suggestion first: I cannot change the font. This is the second time I have had to change fonts for this project to align with brand guidelines. Aptos is the new Microsoft default and a mandatory brand font for these deliverables. My current "workaround" is manually using Find & Replace in PowerPoint to change every rogue "G" and "C" back to "9" and "&", which is incredibly inefficient for a production workflow. I need the Express export engine to map these glyphs correctly.

      Here is the information and files you requested to help the engineering team patch this:

      • Sample PPTX & Screenshots: I have attached the corrupted exported .pptx file, as well as a side-by-side screenshot showing how it looks perfectly fine in the Express web canvas but corrupts upon export. Here is the link to the Express file as well: https://new.express.adobe.com/id/urn:aaid:sc:AP:3bcb58fc-0868-45cc-a5b6-f5f65e5fe767?accept=true&invite=true&promoid=Z2G1FQKR&mv=other

      • Does it occur with all presentations? Yes, it happens on any project that utilises the Aptos font when exported to PPTX. I even had a colleague test this on a completely different machine and account, and they experienced the exact same glyph mapping corruption.

      • Does it persist with other fonts? No. Standard fonts like Calibri or Arial map correctly. The bug is specifically related to how Adobe Express is encoding the Aptos font family (including Regular, Semi Bold, Bold, and Light) into the PPTX XML data.

      • Browser & OS Details: I am using Adobe Express App on Mac 15.5 (24F74)

      Please let me know if your engineering team needs any further diagnostic data to push a fix for this export defect.

      Thanks,

      Adrian
