File name in signed URLs is not URI-encoded

[leonardo-panseri]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

The supabase.storage.from_().create_signed_url() method returns an invalid URL if the file name contains any character that should be URI-encoded.

To Reproduce

1. Create a bucket named my-bucket
2. Upload a file named my file.txt to the bucket
3. Execute this script with the Python client:

response = supabase.storage.from_("my-bucket").create_signed_url("my file.txt", 120)
print(response["signedURL"])

The output is the invalid URL:

https://<supabase_url>/storage/v1/object/sign/my-bucket/my file.txt?token=<token>

Expected behavior

The file name should be URI-encoded before using it to build the URL, for the previous example I expect an output like:

https://<supabase_url>/storage/v1/object/sign/my-bucket/my%20file.txt?token=<token>
