Should dots in regular expressions be allowed when configuring index-level permissions for a role?

Regular expression is available for specifying index-level permissions for a role from this view.

But, when setting a regular expression pattern including dots, the dots are replaced with ‘?’ in the method submitAddIndex.

Then, the pattern created after the replacement is not always a valid regular expression pattern.

For example, when specifying ‘/./’ for the index input, it is replaced with '/?/’ after pushing the save button, where the pattern after the replacement is invalid.

Can this be a bug?

Can we use dots in regular expressions?

How about validating regular expressions before submitting?
