The fixed string size class always adds +1 to a requested string size. Is this really a good idea. I am currently struggeling to read data back with python. The manual recommends to add the +1 for C code in order to have the \0 written at the end of a string. But for languages which do not have a terminal \0 this causes some troubles. I need to think about this during the weekend but we need a quick solution for this. Did we already try to read our data with h5py?
