Description

 

Compiling the code below with groovyc results in the following error message:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Ö_ClassWithUlmaut.groovy: 2: Unexpected input: '(' @ line 2, column 41.
Ö_ClassWithUlmaut getInstance(){
^

1 error

 

The file is encoded in Windows-1252 and I'm compiling it with the following command:
\Tools\groovy-3.0.5\bin\groovyc --encoding Windows-1252 Ö_ClassWithUlmaut.groovy

Compiling with version 2.5.8 works fine

 

The problem only seem to occur when the class name starts with a unicode character i.e. the problem doesn't occur if the class name has an unicode in it as long as it isn't the first character

Example:

class Ö_ClassWithUlmaut {
    static Ö_ClassWithUlmaut getInstance(){
    }
}
