| These Metacharacters offer some powerful solutions to long-standing RegEx problems. These can replace complicated RegEx patterns previously required, and are recommended for use if you are running the required versions. For example, `\h` and `\R`. ICU 55 is _not_ available in all RegEx engines. A notable exception is JavaScript (and JXA), even in High Sierra. So if you are using the native Keyboard Maestro Actions that use RegEx, it would be available, but not necessarily in Actions that use Execute Script in another language. It is available in Execute AppleScript Actions that use ASObjC RegEx. | These Metacharacters offer some powerful solutions to long-standing RegEx problems.
