When e.g. a category contains a ~ in its node name and when it's used in the website in an URI (by means of selector parameter, see info.magnolia.cms.core.Path#SELECTOR_DELIMITER) then the node will not be resolvable, because the tilde will be removed.

How to reproduce

1. Goto STK demo and open categories app
2. Rename a category (e.g. Finance to Finance~) using the ~ character, activate changes
3. Open localhost:8080/magnoliaPublic/demo-project/service/category~Finance~~.html
4. Error will show that category cannot be found

Source

The ~ (tilde) is a reserved character due to being used as selector delimiter (see info.magnolia.cms.core.Path#SELECTOR_DELIMITER).

Considered solutions

• prevent entering the ~ as part of a page name e.g. by validation or
• always sanitize the path (by replacing tilde with e.g. dash) upon storage.
• support both selector or node-name when there's no ambiguity (and specify who should win otherwise)
