<p dir="auto">Technically, yes. <code class="notranslate">%2E</code> is <code class="notranslate">.</code>. See <a href="https://www.ietf.org/rfc/rfc3986.txt" rel="nofollow">RFC3986</a> section 2.1 for details (<em>all</em> ASCII characters can be URL encoded, syntax is <code class="notranslate">%<char hex></code>)</p>
<p dir="auto">Unfortunately, <em>most</em> common URL encoders that people use <em>will not</em> encode <code class="notranslate">.</code> by default.</p>

In either case, doing a string replace of "." with "%2E" will fix the problem, but we would want to document that users <em>must</em> do so.</li>
