Invalid Byte 1 of 1-Byte UTF-8 Sequence on Opening .graphml File #22

Closed LarsaSolidor closed 4 years ago

LarsaSolidor commented 5 years ago

I export a .graphml file using

filename = 'A File Name'
with(open(f{filename}.graphml, 'w') as fp:
    fp.write(g.get_graph())

The resulting .graphml file gives me the following error when opened in yEd:

y.H.B.B.a: SAX error: Invalid byte 1 of 1-byte UTF-8 sequence.

Does your network include any non-ascii characters (e.g., accented characters, ligatures like æ, emojis, or characters from other alphabets)?

LarsaSolidor commented 5 years ago

Hi, I don't think so. The characters in the filepath are:

-.:ACDILOPSTU\_abcdehiklmnoprstuv

With ASCII codes:

[32, 45, 46, 58, 65, 67, 68, 73, 76, 79, 80, 83, 84, 85, 92, 95, 97, 98, 99, 100, 101, 104, 105, 107, 108, 109, 110, 111, 112, 114, 115, 116, 117, 118]
