I am using windows 10

My guess is that you have a BOM in the beginning of your file. I don’t know how to remove it on Windows. Your text editor might have a setting for it. Otherwise you could try to copy-paste the text into another text editor than the one you are using.

Based on some quick experiments, I think Magjac has identified the problem.
If you are using notepad to create your files, do not save as UTF-8 with BOM

p.s. What editor did you use to create this file?
p.p.s. first I’ve heard of BOM, ugh

It may be reasonable to make the cgraph lexical processor more robust to these UTF-8 characters, that can probably be treated as whitespace. I wonder if there are any good articles on best practices to solve this problem.

Thank you everyone! I was able to generate the PNG by changing the encoding to UTF-8. The UTF-8 with BOM was the problem. U was struggling with that for days. So once again I appreciate it.

You were so right bro thanks for the help.

I was just using the notepad app on my computer. And yea when I changed the encoding to a regular UTF-8 that solved the problem

Thank you. As the other people above suggested the UTF-8 with BOM was the problem. I changed it to a regular UTF-8 and that worked.

Its normally just a matter of checking the first 3 bytes for “magic” values, this is what notepad++ does: notepad-plus-plus/Buffer.cpp at 9d69db9b1540500bf360383c2e5b28da67ebcf68 · notepad-plus-plus/notepad-plus-plus (github.com)

This is surprising as Graphviz actually handles UTF-8 BOMs. I’m guessing perhaps Notepad saved the original file in UTF-16.
