A REST function URI or function variable may use special characters, such as pipe (\|)
characters.

When using these characters in a REST message, use URL encoding to escape these characters. For
example, to use a parameter value of user\|title, enter
<kbd class="ph userinput">user%7Ctitle</kbd>. Entering special characters directly may cause the REST
message to fail and display the response Invalid uri \<URI\>: Invalid query.
