This is because you set the configuration using endpoint URI which is encoded according to the standards
http://en.wikipedia.org/wiki/URI_encoding

{quote}
*Current standard*
The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values. This requirement was introduced in January 2005 with the publication of RFC 3986. URI schemes introduced before this date are not affected.

Since the {{%}} char is *not* from the _unreserved set_ it falls into the rule of having to be converted to bytes and then percent-encoded.

So the implementation in Camel is correct.

> But Came only works with the following spec:  fromURL="someQ?selector=CamelFileNameOnly like 'SomeFile%25'"
> In summary the [standard JMS selector wilcard|http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/jms/Message.html] (x like '%y%') is not supported. 
> Instead the % must be encoded as %25 (hex value for %), which is ugly.
