SIP: contact search/add bar filtering issues

I'm looking at using Ring as a SIP client and I seem to have been able to successfully install the 2018.6.6 version from the Gentoo overlay. However, I've been having a couple of problems with adding/searching contacts using the text input at the top left of the interface:

• I can't seem to call any contacts with * in their numbers. This might not be an issue normally since normal phone numbers don't use that character, but my VoIP provider has voicemail set up as *97 and there doesn't seem to be any way to call that number to check my voicemail using Ring. I even tried manually adding a conversation to the database using SQLite and still didn't see it in the list.
• I tried typing a ' into the search box to see if that would let me use special characters like * and it crashed LRC with an SQL error. I suppose that there really aren't any phone numbers with ' in them, but at the same time the fact that Ring uses SQL but doesn't seem to be properly escaping its queries is a major red flag for security-conscious users.
