I have a product with a very weird SKU (which is valid in Magento 2.3.2):
Although, REST API requires using SKU as a part of URL to get the stock item info. How is it possible to use that SKU as a part of URL? If I don't encode it, it is, obviously, invalid URL. If I encode it, I'm getting an error:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL was not found on this server.</p>
</body></html>
