`TextDecoder` does not respect `DataView` offset and length

[zhuzhu81998]

Similar to #4615 :

const buffer = Uint8Array.of(0x42, 0x42).buffer;

// Create a DataView that starts at byte offset 1
const view = new DataView(buffer, 1);

console.log(new TextDecoder().decode(view));

Expected: B, actual: BB.

Let us handle this after #4766 .

Hi 👋,

I’m interested in working on this issue.

From the example, it looks like TextDecoder.decode() is ignoring the DataView’s byte offset and decoding the entire underlying buffer instead of respecting the view range.

I understand that this will be handled after #4766 is resolved. Once that issue is addressed, I’d be happy to investigate this and propose a fix.

Please let me know if there’s anything specific I should review before starting.

Thank you!

#4787 is not yet merged, but you can already branch out from there and do your changes. should be fairly straightforward.
