             Summary: CAnnot create unicode sequences using \Uxxxxxx
                 Key: GROOVY-7727
                 URL: https://issues.apache.org/jira/browse/GROOVY-7727
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.4.5
            Reporter: Andres Almiray


According to http://www.oracle.com/technetwork/articles/java/supplementary-142654.html 

"For text input, the Java 2 SDK provides a code point input method which accepts strings of the form "\Uxxxxxx", where the uppercase "U" indicates that the escape sequence contains six hexadecimal digits, thus allowing for supplementary characters. A lowercase "u" indicates the original form of the escape sequences, "\uxxxx". You can find this input method and its documentation in the directory demo/jfc/CodePointIM of the J2SDK."

The following code fails with a syntax exception

    s = "\U01f5d0"
