How can I fix the UnicodeDecodeError in gcloud app deploy due to non-UTF8 filenames?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm deploying an application using the command gcloud app deploy and encountered the following error:
utf-8' codec can't decode byte 0xa2 in position 37: invalid start byte
This error suggests that one or more file or directory names in my container are not encoded in UTF-8, which is required by Google Cloud environments. I've double-checked my deployment command and source files, but the problem persists. Could someone guide me on how to identify and fix non-UTF8 encoded file names to successfully deploy my application?

The error indicates that one or more file names in your container are not encoded in UTF-8. Google Cloud environments—especially Cloud Run—require that container file names be in valid UTF-8 format. Although the error you encountered came during an App Engine deployment (gcloud app deploy), the same underlying issue can occur if non-UTF8 filenames exist in your container image.
How to resolve this issue:
-
Check your container file names:
Ensure that every file and directory name within your container uses UTF-8 characters only. -
Build containers on a UTF-8 compliant machine:
If you build your image on a machine that supports UTF-8, it’s more likely that all file names will automatically be encoded correctly. -
Audit your source files:
Sometimes files brought in from different environments (for instance, Windows systems) might inadvertently have non-UTF-8 compliant naming. Review and rename such files as needed.
Once you correct the encoding issue, you should be able to deploy without encountering the UTF-8 decoding error.
