I hope this message finds you well. I am writing to bring your attention to a bug that I encountered while using your software. Specifically, I have come across an issue where certain Japanese fonts are not displayed properly in PDF files.

After some investigation, I have found that the issue can be fixed by making the following modifications to your Forge component:

1. In viewer.js, line 4329:

   - Current code: value: '../web/cmaps/'

   - Proposed code: value: '../cmaps/'

2. Add the following file:

   - ja.viewer.properties.txt

   - This can be obtained from the PDF.js GitHub repository.

I understand that your time is valuable, but I would greatly appreciate it if you could consider making these changes to your software. Please let me know if you have any questions or require any further information.

Thank you for your attention to this matter.

Best regards,
