Describe the issue or problem
I tried to upload a new issue galley PDF to an existing issue and this error message appears:
This can only contain letters, numbers, dashes and underscores.
But the PDF title only contains the demanded characters?!
Steps I took leading up to the issue
I think the error is similar to this solved problem Issue galley locale error but my programming skills are not good enough to solve this bug alone. So maybe @bozana can help?
What application are you using?
