When you use batch rename you can ask him to rename to invalid node names. it won't raise any warning nor error it will just rename to a valid node names without informing you of the change. For comparison with simple renames this is shown as warning

### Steps to reproduce

1. create a root Node and two Node children
2. select the two children
3. Batch rename the `e` to `%`
4. See that childrens have been renamed to `Nod_` and `Nod_2` without warning
