Hi All, I encounter a error recently, and it will result in abnormal patch, abnormal CI build and abnormal edk2-devel message. You can run ``` git config sendemail.transferencoding 8bit``` to avoid the error. The detail information as below, When I ready a patch and send it to devel@edk2.groups.io, will see below abnormal picture. >From Mail: [cid:image001.png@01D61D85.07F968D0] >From groups.io [cid:image002.png@01D61D86.BD272250] >From CI: [cid:image003.png@01D61D86.BD272250] The defect happened because of CR+LF is keep in patch and will keep in mail, it seem that the CI or groups system haven't dispose it correctly. I get the answers from https://stackoverflow.com/questions/6289001/git-am-format-patch-control-format-of-line-endings, and bit8 can avoid unnecessary CR when send email. It explain the history why import the option as well. https://git-scm.com/docs/git-send-email provide the usage for the option. Help it is useful for yours Best Regards guomin
