<i>curl gets confused by non-ASCII letters in the path part but percent encodes such byte values in the outgoing requests – which causes “interesting” side-effects when the non-ASCII characters are provided in other encodings than UTF-8 which for example is standard on Windows…</i><p>I don&#x27;t think cURL implements this percent encoding yet - instead, it sends out binary paths on UTF-8 locale and Linux likewise. This was recently added in cURL&#x27;s TODO though: <a href="https:&#x2F;&#x2F;curl.haxx.se&#x2F;docs&#x2F;todo.html#Add_support_for_IRIs" rel="nofollow">https:&#x2F;&#x2F;curl.haxx.se&#x2F;docs&#x2F;todo.html#Add_support_for_IRIs</a>
