When uploading a document whose filename contains diacritics or special characters (such as á, é, ñ, ç, ü), the AI models respond that they cannot access the requested file. The upload itself may succeed, but subsequent analysis or queries about the file fail.

So far, I've had to manually rename the file to remove all diacritics and special characters before uploading it for analysis.
Files with diacritics and common special characters in their names should be accessible and analyzable by the AI models after upload, without requiring manual renaming prior to uploading.
