Blob download encoding

[Christoph Taucher]

Problem
If a Blob is created the bytes their encoding is wrong.

Steps To Reproduce

1. Create a Blob with a String ("Test") as content
2. Create a Url from the Blob

use web_sys::{js_sys::Uint8Array, Blob, BlobPropertyBag};
use yew::prelude::*;

#[derive(PartialEq, Properties)]
pub struct DownloadBlobProps {
    pub text: String,
}

#[function_component]
pub fn DownloadBlob(props: &DownloadBlobProps) -> Html {
    let array_buffer = props.text.clone().into_bytes();
    let uint8_array = Uint8Array::from(array_buffer.as_slice());

    let blob = Blob::new_with_u8_array_sequence_and_options(
        &uint8_array,
        BlobPropertyBag::new().type_("text/plain"),
    )
    .expect("Failed to create Blob");
    let url = web_sys::Url::create_object_url_with_blob(&blob)
        .expect("Failed to create object URL from Blob");

    html! {
        <a
            href={url}
            download="file.txt"
        >
            { "Download File" }
        </a>
    }
}

4. Download the file provided by the Url
5. The Provided String Value "Test" is shown as "84101115116" in the File

Expected behavior
The File should have the provided String value as Content.

Environment:

• Yew version: v0.21, master
• Rust version: 1.75.0
• Build tool, if relevant: trunk
• OS: Windows 10
• Browser and version: Brave 1.63.165 Chromium 122.0.6261.94, Firefox 123.0, Edge 122.0.2.2365.66

Minimal Example Code to reproduce: yew-blob-download-bug.zip

I also tried different methods to Encode and Blob creation but without success.
