The background is, that I want to change the padding type from H5T_STR_NULLTERM to H5T_STR_SPACEPAD. I have found some Discussions about that which I not fully understand (https://github.com/PyTables/PyTables/issues/264
). I understand it the way that there is no possibility in pytables to store the data as H5T_STR_SPACEPAD and I have to switch to h5py to bypass the problem. But the discussion is from 2013 and maybe the situation has changed until now. Then I found the supported datatypes and was confused - so is it possible to change the type in pytables?
