So, even with the code above that doesn't use Pydantic explicitly, FastAPI is using Pydantic to convert those standard dataclasses to Pydantic's own flavor of dataclasses.

And of course, it supports the same:

* data validation
* data serialization
* data documentation, etc.

- Object name restrictions on MinIO are governed by OS and filesystem limitations. For example object names that contain characters `^*|\/&";` are unsupported on Windows platform or any other file systems that do not support filenames with special characters.

> **This list is non exhaustive, it depends on the operating system and filesystem under use - please consult your operating system vendor for a more comprehensive list of special characters**.
