Insert a Unicode Identifier Status or Type

A Unicode identifier status and identifier type are two of the many Unicode properties that you can insert via the Insert Token button on the Create panel.

Every Unicode code point has exactly one value for the Identifier_Status property and another value for the Identifier_Type property. These properties are used in Unicode Technical Standard #39 (UTS 39): Unicode Security Mechanisms. RegexBuddy provides a single menu item for inserting these because the two properties are closely related. The item you select in the list determines both which of the two properties your regex needs to match, and which value for that property it needs to match.
