Handling of special characters
Normally I use graphviz with the tool 'gvedit 1.01' that is part of the Windows installation of graphviz. Now, because of a certain demand described in forum topic "Different spline-styles on different levels not possible?", I had to use the command line version of 'dot'. When processing my gv-file with 'dot' I've got this warning:
(dot.exe:5472): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()
In my input-file I use the Ascii-Character 133 (three dots in a row) for some labels.
So the gv-file looks like this (I hope that the charater "..." between A and B will be visible after saving this posting):
C [label = "A…B"];
A -> C [splines = "true"];
B -> C [splines = "false"];
But the result when using the command line call of 'dot' shows a different character (a box with a cross). Only when I call dot from 'gvedit' I get the desired result. In the past I also created graphviz-files with cyrillic unicode characters in the labels of the nodes. This was no problem when I opened the files in 'gvedit'. But I just made a test with comand line dot and got the message:
Warning: ju.gv:1: syntax error in line 1 near '´╗┐Digraph'
Why do I get these different results?
Is there any way to influence the way, 'dot' handles special characters and unicode files?
