charset=UTF-8 does not work

[ygra]

There's a sample linked from the documentation:

http://magjac.com/graphviz-visual-editor/?dot=digraph%20G%20%7b%0a%20%20charset%3d%22UTF-8%22%0a%20%20%f0%9f%8d%94%20-%3e%20%f0%9f%92%a9%0a%7d

which immediately raises an error, even though as part of the official documentation, that should probably work.

I agree this is a bug. I wonder if it's possible that this is an upstream bug which is now fixed. I'll attempt an upgrade.

Judging from the parser source code, could it be that code points outside the BMP aren't even supported? The parser looks at individual UTF-16 code units and doesn't appear to consider surrogates at all.

This is a bug in the Graphviz Visual Editor itself, not an upstream bug.

A workaround is to quote the node names like this:

digraph G {
  charset="UTF-8"
  "🍔" -> "💩"
}
