Please let me know if you can correct for this, or should I somehow edit the file manualy

 

Many thanks,

Answer 1

This error message means that there is a character/letter in the GraphML file that should not be in there (according to the error message it is the unicode character at codepoint 0 in line 258589). In theory, the quick fix would be finding and removing that character manually. However, unicode codepoint 0 is an "invisible" character that is not displayed in text editors which makes it difficult to find the offending character.

How did you create the problematic file? Which version of yEd are you using? What version of Java is yEd running on?

Your file seems to be really big, so uploading here is probably not an option. If you can upload your file to a public file hosting site and post a link to your file here, I will have a look and try to remove the problematic characters.

Thank you for your quick reply.
I'm using yEd version 3.14 on Java 1.8.0_25 on Windows 7 x64,
although the file is quite old (~6 months old) so it was created in one of the previous versions of yEd. I didn't change anything substantial in the file. Just edited some text in the node and than the next time I tried to open the file I could not. I certainly didn't edit it by hand. I will look for the character myself, as the file contains somewhat personal information.
