Fix NXscanH5_FileRecorder.addCustomData() with strings (!1485) · Merge requests · Sardana Organization / sardana

Zbigniew Reszela requested to merge github/fork/reszelaz/str_addCustomData into develop Jan 26, 2021

https://github.com/sardana-org/sardana/issues/771#issuecomment-734743646 reports a bug with saving string custom data. This PR fixes it. @dschick, the workaround from https://github.com/sardana-org/sardana/issues/771#issuecomment-736360038 is not necessary anymore. @sardana-org/integrators could you please take a look on this one?

Note that in h5py 3.x they changed some recommendations for storing string data, but this PR still uses the recommendations from h5py 2.x that we used in the past.
