A number of our Jira issues include comments where the commenter used the (x), (!), (?), (i), and (/) icons within the body of the comment. We would like to be able to build a filter to find only issues with comments that include one of those icons. I've tried the obvious JQL searches like comment ~ "(/)" or comment ~ "(?)", etc... with varied results depending on the symbol used. for example, i don't get an error using x, i, or / but the search doesn't find the right issues. if I use ? or !, it fails altogether. Any recommendations?
