Incorrect rendering of labels with percent (%) sign
I need to render in a directed graph labels with the percent (%) sign.
My expectation is that if I quote them with double quotes, they should be correctly rendered.
What happens, however, is that they are garbled.
Here is an example:
andrea@SPADACCIO-LAP:~$ dot -V
dot - graphviz version 2.40.1 (20161225.0304)
andrea@SPADACCIO-LAP:~$ cat test.dot
digraph g {
"%foo%" -> "bar"
}
andrea@SPADACCIO-LAP:~$ dot -Tpng <test.dot > test.png
Output (test.png):
Am I missing something? Thanks!
