When adding a new node, Jenkins will happily let you have a name with brackets in it: '(' or ')'

For example:

However, if I try to set the restrict where job is run field and tie a job to the new node then there is a parsing error (invalid boolean expression: unexpected token).

Error message:

I suggest that the original node creation process prevents users from using reserved characters.

or...

The restrict where project can be run parsing logic is updated to handle the list of allowed characters.

Thanks!
