Does anyone know if this uses ICU under the covers? Is that affected too?

I don't believe that's the case, looking at the commit [0]

Interesting. The reason for a bug seems to be that ^ and $ in regexps match a boundary of any line, not boundaries of a string. This have already caused problems in the past, as far as I remember, but Ruby developers didn't change the behaviour of these characters.

So if you write a regexp like /^[0-9]$/, a string "Any characters\n12345\nAny characters" will match the regexp.

because Ruby has \A and \Z to match the boundaries of a string
