+// LoadStrategy returns a loader function for a given path or URI.
+//
+// The load strategy returns the remote load for any path starting with `http`.
+// So this works for any URI with a scheme `http` or `https`.
+//
+// The fallback strategy is to call the local loader.
+//
+// The local loader takes a local file system path (absolute or relative) as argument,
+// or alternatively a `file://...` URI, **without host** (see also below for windows).
+//
+// There are a few liberalities, initially intended to be tolerant regarding the URI syntax,
+// especially on windows.
+//
+// Before the local loader is called, the given path is transformed:
+//   - percent-encoded characters are unescaped
+//   - simple paths (e.g. `./folder/file`) are passed as-is
+//   - on windows, occurrences of `/` are replaced by `\`, so providing a relative path such a `folder/file` works too.
+//
+// For paths provided as URIs with the "file" scheme, please note that:
+//   - `file://` is simply stripped.
+//     This means that the host part of the URI is not parsed at all.
+//     For example, `file:///folder/file" becomes "/folder/file`,
+//     but `file://localhost/folder/file` becomes `localhost/folder/file` on unix systems.
+//     Similarly, `file://./folder/file` yields `./folder/file`.
+//   - on windows, `file://...` can take a host so as to specify an UNC share location.
+//
+// Reminder about windows-specifics:
+// - `file://host/folder/file` becomes an UNC path like `\\host\folder\file` (no port specification is supported)
+// - `file:///c:/folder/file` becomes `C:\folder\file`
+// - `file://c:/folder/file` is tolerated (without leading `/`) and becomes `c:\folder\file`
