> % char in an href will not be escaped by sightly. This will cause an issue in
> case a space is immediately after it, e.g.
> "?message=5% fat only" will be escaped like "5%%20fat%20only", and %%20 will
> crash some servers' request processing, at least it crashes sling's with
> something like:
> {noformat}
> org.apache.sling.engine.impl.parameters.ParameterSupport
> getRequestParameterMapInternal: Error parsing request
> java.lang.IllegalArgumentException: Bad escape sequence: %=l
