[erlang-questions] Atom Unicode Support

[José Valim]

The comparison on binaries are done at the byte level, so there is no
collation. Lists (strings) compare integer codepoints, so no collation as
well. Atoms are also byte-oriented, I believe, but we will have mixed
encoding because "josé" will be encoded as latin1 if possible, so no
collation either.

I believe the default comparison rules won't change. Collation support
needs to be provided as a library.
