[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Bug Report

go.mod has:

github.com/Azure/azure-sdk-for-go/sdk/azcore v1.18.0
github.com/Azure/azure-sdk-for-go/sdk/storage/azblob v1.6.1

• What happened?

  Tried to delete a nonexistent blob with a tab in the blob name, only to get:

DELETE https://***.blob.core.windows.net/***/test/8d2c49bac5508e462cfe/1b4065bd5a50da115809	1a72b71e016e13da895d

• What did you expect or want to happen?

  A 404.

• How can we reproduce it?

  By putting a tab character anywhere in the blob name, path encoded. The above was setup like:

blobURL := containerURL + "/" + prefix + "/" + url.PathEscape(blobName)
client := blockblob.NewClientWithSharedKeyCredential(blobURL, cred, o)

and before the client.Delete(), the client.URL() looked like:

https://***.blob.core.windows.net/***/test/8d2c49bac5508e462cfe/1b4065bd5a50da115809%091a72b71e016e13da895d

• Anything we should know about your environment.

  This was a test case, but we do have a file in azure that somehow got a tab in the blob name, which we cannot now access.

Fixes #24562.
