### Bug description When a chart or dashboard title contains non-printable control characters—specifically the Backspace character (U+0008 / \x08)—the Image/PDF export feature (powered by Playwright/Selenium headless browsers) fails. These characters are often inadvertently included when users copy and paste text from external sources (e.g., legacy systems, spreadsheets). While they are invisible on macOS, they appear as small boxes on Windows and cause the headless browser used for reports/thumbnails to hang or crash during the rendering process. testtest ### Screenshots/recordings <img width="1325" height="748" alt="Image" src="https://github.com/user-attachments/assets/c7a70174-d6c8-4759-b919-449c678e82e6"; /> ### Superset version 6.0.0 ### Python version 3.11 ### Node version 18 or greater ### Browser Chrome ### Additional context _No response_ ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [ ] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
