-     * Escape invalid URI characters.
-     *
-     * Passed a URI that contains invalid characters (like spaces, non-ASCII Unicode characters, and the like),
-     * this function percent encodes the invalid characters per the URI specification (i.e., as a sequence of
-     * %-encoded UTF-8 octets).
-     *
-     * N.B. There are two problems. If the URI contains a '%' character, that might be an indication that
-     * the URI has already been escaped by the author, or it might be an invalid '%'. In the former case,
-     * it's important not to escape it, or we'll wind up with invalid, doubly-escaped '%'s. In the latter,
-     * the URI is broken if we don't encode it. Similarly, a '#' character might be the start of a fragment
-     * identifier or it might be an invalid '#'.
-     *
-     * Given that the former is vastly more likely than the latter in each case (most users are familiar with
-     * the magic status of '%' and '#' and they occur relatively infrequently in filenames, and if the user parses
-     * a proper Java File, we will already have %-escaped the URI), we simply assume that %'s and #'s are legit.
-     *
-     * Very rarely, we may be wrong. If so, tell the user to fix the clearly broken URI.
