- Product
- Adobe Document Cloud / Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Downloading a shared PDF document containing non-English (Russian) review comments from Adobe Document Cloud to a local device.
- Observed behavior
- The comments appear perfectly readable while viewing the document online, but exhibit incorrect character encoding once the PDF is downloaded and opened locally.
Verify that your computer's system language settings support Cyrillic characters and ensure you are using a stable internet connection to prevent file corruption during the download.
Update Software and Verify Font Compatibility
Updating your PDF viewer and ensuring the document uses standard Unicode fonts are the most effective ways to correct rendering and encoding bugs.
Incorrect text rendering is often caused by outdated software versions struggling to parse non-English annotations or the absence of standard Unicode fonts embedded in the document.
Launch Adobe Acrobat, click on the 'Help' menu at the top, and select 'Check for Updates'. Ensure your web browser used to download the file is also updated to its latest version.
Open the PDF document and inspect the comment properties. Ensure that the text utilizes a Unicode-compatible font (such as Arial, Calibri, or Times New Roman) that broadly supports Cyrillic characters.
Right-click the downloaded PDF file, select 'Open with', and choose a different application such as WPS PDF or your web browser to determine if the encoding problem is isolated to Adobe Acrobat.

Escalate the Issue to Adobe Support
If troubleshooting locally does not resolve the encoding problem, gather your diagnostic files and reach out to the software vendor.

Frequently Asked Questions
Why do PDF comments display as strange or garbled characters?
This usually happens when the text is not encoded in a standard Unicode format, the font used in the original document is missing from your system, or your PDF viewer has an unresolved rendering bug for specific languages.
Can I use a different PDF viewer to fix text encoding issues?
Yes, opening the downloaded PDF in another reader, such as WPS PDF or your web browser's built-in viewer, can often bypass rendering bugs isolated to a specific software and display the text correctly.
How do I ensure Cyrillic text displays correctly in exported PDFs?
Always use universal, Unicode-compatible fonts like Arial or Times New Roman when writing comments. Additionally, check that the source application is properly configured to embed fonts when exporting to PDF.
