-----------------------------------
Here are some uppercase letters:
{code}
println '''
\u00C0\u00C1\u00C2\u00C3\u00C4\u00C5\u00C6\u00C7\u00C8\u00C9
\u00CA\u00CB\u00CC\u00CD\u00CE\u00CF\u00D0\u00D1\u00D2\u00D3
\u00D4\u00D5\u00D6\u00D8\u00D9\u00DA\u00DB\u00DC\u00DD\u00DE
'''
{code}
which produces:

> Compilation failure when using non-ASCII chars as method return type
> --------------------------------------------------------------------
>
> Key: GROOVY-7435
> URL: https://issues.apache.org/jira/browse/GROOVY-7435
> Project: Groovy
> Issue Type: Bug
> Components: parser
> Affects Versions: 2.1.6, 2.4.3
> Reporter: Rodolfo Cruz
> Priority: Critical
> Attachments: InternationalizationTest.groovy
>
>
> When trying to declare the return type of a method having non-ASCII
> characters, such as in the following example:
> {code:title=InternationalizationTest.groovy|borderStyle=solid}
> @groovy.transform.ThreadInterrupt
> @groovy.transform.TypeChecked
> public class 对象 {
> public 对象 get对象()
> {
> return new 对象()
> }
> }
> def myVar = new 对象()
> {code}
> the compilation fails with the message:
> {{unexpected token: public at line: 6, column: 1}}
> Those characters are valid according to the [official
> documentation|http://docs.groovy-lang.org/latest/html/documentation/#_identifiers]
> and using them in other places such as a class or variable declaration works
> as expected.
> I'm attaching the example in order to provide an easy way to test the issue.
