Hi, first I want to thank all involved in developing git. It is really one of the - no! - it is the greatest tool I ever worked with! So I want to help improving it at least with this bug report. Since git version 2.9.0 git git-gui messes up my author name - which contains UTF-8 characters: Silvester Rößner - when I amend a commit. When I do the same with git-bash it's all ok. git log after first amend: $ git log commit 8ac8115c3af04bd8f5171452141398b0cfb57f87 Author: Silvester RöÃ?ner <silvester.roessner@xxxxxxxxx> Date: Wed Jun 29 07:31:46 2016 +0200 asdf commit ae34f23a9a3d7f673ad3ed57dbea5af302d4f0c1 Author: Silvester Rößner <silvester.roessner@xxxxxxxxx> Date: Wed Jun 29 07:31:21 2016 +0200 test git log after second amend: $ git log commit 9240372e8e7336a2c523f27a75b3ac4e07315039 Author: Silvester RÃ?¶Ã??ner <silvester.roessner@xxxxxxxxx> Date: Wed Jun 29 07:31:46 2016 +0200 asdf commit ae34f23a9a3d7f673ad3ed57dbea5af302d4f0c1 Author: Silvester Rößner <silvester.roessner@xxxxxxxxx> Date: Wed Jun 29 07:31:21 2016 +0200 test To reproduce the bug 1. create an empty repo, 2. set up the author name to "Silvester Rößner" 3. commit a file with git gui 4. amend the commit with git gui I use this version git-gui version 0.20.GITGUI git version 2.9.0.windows.1 Tcl/Tk version 8.6.5 The versions I used before just work great!
