Invalid regular expression error

[juniusfree]

Problem

To replicate:

1. Create a new page with a bold title (e.g. [[**new page**]])
2. Open the page
3. Remove the "**"
4. Click outside the textarea

Another way to replicate:

1. Search for a block using block reference using this value: ((**))
2. Click any of the blocks that will appear on the inline search

Screenshots/Demo Error on page title:

Error on inline search for block

I investigated for a bit and it looks like this is related to the linked function in patterns.cljc. https://github.com/athensresearch/athens/blob/566c678bcfdf486641e0cf4cd2ab3957f0e65761/src/cljc/athens/patterns.cljc#L6-L10

Athens Version 1.0.0-BETA.40

Additional observation: The empty page name is saved after editing. Is this an expected behavior?

This is probably the same issue - when you open the "find or create a page" dialog then type "C+", you will get the same error. Seems like the fix is being merged soon...

I've observed similar issues typing a slash followed by a parenthesis. See the following screenshot:

I am having the same issue when deleting a page named TODO\
