### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

First, I upload a file that includes spaces in its filename.

Then, when I try to copy that file, I get a 404 error, and the file is not copied.

```
2024/01/04 21:31:18 error s3client copy object: operation error S3: CopyObject, https response error StatusCode: 404, RequestID: 81bbb363-4bf9-49ac-ac4e-fe4918a9a09c, HostID: s9lzHYrFp76ZVxRcpX9+5cjAnEH2ROuNkd2BHfIa6UkFVdtjf5mKR3/eTPFvsiP/XV/VLi31234=, api error NoSuchKey: The specified key does not exist.
Exiting.
```

### Expected Behavior

The file should be copied successfully.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

```docker-compose.yml
version: '3.9'
services:
  localstack:
    build:
      context: localstack
      dockerfile: Dockerfile
    environment:
      - AWS_DEFAULT_REGION=ap-northeast-1
      - AWS_DEFAULT_OUTPUT=json
      - AWS_ACCESS_KEY_ID=dummy
      - AWS_SECRET_ACCESS_KEY=dummy
      - LOCALSTACK_SERVICES=s3,ses
      - LS_LOG=debug
      - DEBUG=1
    ports:
      - "4566:4566"
```

```Dockerfile
FROM localstack/localstack:latest

COPY ready.d /etc/localstack/init/ready.d
```

Here is the complete code:

git clone https://github.com/yuki2006/localstack_check
go run main.go

### Environment

```markdown
- OS: docker image localstack/localstack
- LocalStack:latest
```


### Anything else?

This is the implementation following the example provided here:
https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/go/example_code/s3/s3_copy_object.go#L65C36-L65C47

(https://github.com/yuki2006/localstack_check/blob/master/main.go#L79)

Additionally, this issue does not occur with the actual S3; no errors were encountered.
