Description

I was surprised to find out that this function does not URL-encode passed parameters for me. I'm now having to go through my codebase and manually encode things, after an un-encoded value sent users to an invalid URL.

At the very least, the documentation should mention this shortcoming.

Ideally, a fourth argument would be added to route() to enable proper URL encoding. Something like:

function route(
    BackedEnum|string $name, 
    mixed $parameters, 
    bool $absolute = true, 
    bool $encode_params = false
): string

Steps To Reproduce

Route::get('/e/{data}')->name('test');

echo route('test', ['data' => 'foo/bar']);

Result: /e/foo/bar

Expected result: /e/foo%2fbar
