The Phobos Unicode methods (such as std.uni.isAlpha()) are compatible with Unicode 6.2 (i.e. the 2012 standard, which is now nearly 5 years old). Unicode is now up to version 9.0. The Unicode changes do include changes to std.uni.isAlpha(), and other methods.

Unicode is now at version 13 and 14 is in work.
* update std.uni to the latest official release.
* since further updates are coming, a process what steps are necessary to keep in sync with the official releases should be created.
