Some of these are just static strings, including the Korean string "국가유공자 장례는 보훈상조" ("Patriots' funeral services are provided by Bohun Sangjo.", Via Kagi) and a number of double-escapes like \\[, along with my personal favourite email validator @. With the substring matching semantics outside of pattern= this would actually be pretty decent email validation, but for patterns this would match only one string: a single @.
