Columns of type characters converted into byte string

[mdmanurung]

Dear author,

I noticed variables of my cell metadata with character type were converted into byte string (b'' surrounding the entries). I could fix this by applying .str.decode('utf-8') to the affected columns. Leaving the columns as byte caused scanpy to fail in detecting those (e.g. when selecting argument for color for plotting functions).

Regards,
Mikhael
