`.` isn't a reserved character in URLs, so it doesn't make sense to URL Encode it. — Quentin, Sep 29 '11 at 10:06

Even if you encode . in JavaScript, the browser is allowed to unencode it before sending it to a server.

RFC 3986 section 6.2.2.2. Percent-Encoding Normalization says

The percent-encoding mechanism (Section 2.1) is a frequent source of variance among otherwise identical URIs. In addition to the case normalization issue noted above, some URI producers percent-encode octets that do not require percent-encoding, resulting in URIs that are equivalent to their non-encoded counterparts. These URIs should be normalized by decoding any percent-encoded octet that corresponds to an unreserved character, as described in Section 2.3.

'.' is an unreserved character in URLs.

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
