Hello,
I would like to use the method sage.graphs.graph_list.from_graph6()
However, it seems that there is some problem. For example, with this file: users.cecs.anu.edu.au/~bdm/data/chordal4.g6
I got the runtime error
RuntimeError: the string seems corrupt: valid characters are ?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_`abcdefghijklmnopqrstuvwxyz{|}~
However, I don't see any invalid character...
Is there something I miss? Best
