Files with long names attached through BPM notifications are not attached on Invoice

Summary:

We noticed that some files attached through BPM notifications (coding or approval) were not getting attached on the invoice. On further investigation we realized that files with shorter names were getting attached through BPM and files with very long names were not getting attached through BPM. What is the maximum allowed length for file names attached through BPM notification?

By trial and error we arrived at somewhere around 80 characters but is there official/documented maximum length for file name?
