Troubleshoot Unicode File Name Display Issues

Since Acrobat.com natively supports Unicode file names, any display issues are typically caused by local browser, operating system, or language settings.

Acrobat.com is fully equipped to handle non-ASCII characters. If your files display with garbled text or question marks, the problem usually lies in how your local environment interprets the characters. Adjusting your system settings can easily resolve this.

1
Check your browser encoding

Go to your web browser's settings and ensure the default character encoding is set to UTF-8, which is the standard for rendering Unicode characters.

2
Verify OS language settings

Navigate to your operating system's region and language settings to confirm that it supports the specific non-ASCII characters you are using in your file names.

3
Clear browser cache

Clear your browser cache and cookies, then refresh Acrobat.com to see if the file names render correctly.

Troubleshoot Unicode File Name Display Issues
Native Support: Acrobat.com fully supports Unicode natively, meaning files named with non-ASCII characters should upload and function normally without requiring you to rename them to standard English letters.

Frequently Asked Questions

What are Unicode characters in file names?

Unicode characters include non-ASCII symbols, such as letters from non-English alphabets (like Chinese, Arabic, or Cyrillic), accented letters, emojis, and special mathematical symbols.

Why do my file names look like random symbols on Acrobat.com?

This usually happens when your web browser or operating system does not have the correct language pack installed, or is failing to use UTF-8 encoding to correctly read the Unicode file name.

Do I need to rename my files to English letters before uploading to Acrobat?

No, Acrobat.com fully supports Unicode file names, so you can upload your documents with their original non-ASCII names completely intact.
