Greek characters are not decoded correctly

[dmalzl]

To proceed with my work I quickly just copied the relevant code from your package and adapted it where needed for my problem. In the course of this I noticed that there seems to be a problem with the character encoding in the ARCHS5 file. I basically decode the metadata similar to you by using

[x.decode('utf-8') for x in table[key][:]]

However, some characters are not decoded correctly, specifically this seems to affect greek letters as the examples I encountered until now are the letter mu and the letter beta (but might not be limited to them). I tried several other encodings but was not able to decode it properly. Could you have a look or at least tell me the right encoding?
