Review comment:
Isn't this too complicated ? I tried and changed this code by adding here:
```
String orig = new String(buffer.unsafeGetMemory(0,out.end));
String upp = orig.toUpperCase(/*Locale.GERMAN*/);
buffer.setBytes(0,upp.getBytes(),0,out.end);
```
and then commented out the whole following *for* loop, and the test passed!
(not sure which one performs better)
