Do people here agree that PHP should have a *policy* of using a consistent Unicode version? This appears to be easy to accomplish for the moment. Moving to Unicode 8 will be harder.

I agree with the policy -> good idea. But I think there will be a lot of problems, when staying on Unicode 7. Since Unicode 8 has the new emoji (colors) and that is used more and more.

The new emoji are neat and people can and should use them. They just can't expect intl or preg to recognize them until some release after 7.0.0. Using Unicode 8 uniformly involves moving to PCRE2, which doesn't seem easy. It's a big API change for little functional gain. I'd like to see PCRE2 implement a bit more of TR18 but I doubt it's a priority. ICU regex as the next big thing in intl is an interesting idea. I've no idea how hard it is. http://unicode.org/reports/tr18/ So Unicode 8 depends on what PHP does about regex going forwards. I asked about this on Sep 24 but got no response. http://www.serverphorums.com/read.php?7,1303221 Tom
