About unicode sequence support in groovy source code

Hi all,

       Groovy supports some strange features on unicode:

1) Declaring identifier with unicode sequences , e.g.  `def \u4e00\u9fa5 =
123`
2) All source code is written in unicode sequence, e.g. `\u0064\u0065\u0066
\u0061 \u003d \u0031\u0032\u0033`, the corresponding readable code is `def a
= 123`

       They seems useless and impacts the performance of parsing, so I am
going to stop supporting it in 2.6.0+.

       Any thoughts?

Cheers,
Daniel.Sun

After discussed with Paul, unicode sequence identifiers can be preserved via
unicode reader as the old parser does.

In addtion, unicode sequences like `\uuuuuuuuuu9fa5` is allowed in Groovy...
I am going to deprecated it too.
