Dashboard title with space #14820

Summary

It is possible to create several custom Dashboard without any restriction into the title of them.

Current behavior

When I create a new Dashboard with a space into the title, the space is encoded (replaced by a %20)

Expected behavior

Several possibilities are available

1. Prevent user to create a Dashboard with some special chars (useless because the dashboard title is not used into the URL)
2. Allow special char but display them without encodage

Thanks @Laul0 I can reproduce that 👍
