Subject: [stdlib, kernel] Introduce Unicode support for Erlang source files

Expect modifications, additions and corrections.

There is a kludge in file_io_server and
erl_scan:continuation_location() that's not so pleasing.

+    <p>In Erlang/OTP R16 the syntax of Erlang tokens was extended to
+       handle Unicode. To begin with the support is limited to strings,
+       but Erlang/OTP R18 is expected to handle Unicode atoms as well.
+       More about the usage of Unicode in Erlang source files can be
+       found in <seealso
+       marker="stdlib:unicode_usage#unicode_in_erlang">STDLIB's User'S
+       Guide</seealso>. The default encoding for Erlang source files
+       is still Latin-1, but in Erlang/OTP R17 the default encoding
+       will be UTF-8. The details on how to state the encoding of an
+       Erlang source file can be found in <seealso
+       marker="stdlib:epp#encoding">epp(3)</seealso>.</p>
