I'm using the name "Extended Identifiers" for the feature because that's
what GCC calls them. According to the standard, the new feature is
"universal character names are now allowed in identifiers", but the more
interesting "feature" is that identifiers can now contain Unicode characters,
however they are written.

+Extended Identifiers: Unicode Support and Universal Character Names
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Clang 3.3 includes support for *extended identifiers* in C99 and C++.
+This feature allows identifiers to contain certain Unicode characters, as
+specified by the active language standard; these characters can be written
+directly in the source file using the UTF-8 encoding, or referred to using
+*universal character names* (``\u00E0``, ``\U000000E0``).
