Description

When compiling this code with Groovy 1.7.3:

class One {
	 /*\u00E9*/ Stack<F> plates;
}

I get the following error message:

$ groovy One.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/private/tmp/One.groovy: 2: unable to resolve class F 
 @ line 2, column 15.
   	 /*\u00E9*/ Stack<F> plates;
                 ^

1 error

I would expect the ^ to be under the 'F'. It appears that the unicode sequence is being considered a single character, rather than 6 characters.
