https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220009 Bug ID: 220009 Summary: stty iutf8 not supported Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: rtc@helen.plasma.xg8.de Linux has a stty setting iutf8. This is necessary for utf-8 locales for the following reason: When you enter a non-us-ascii utf-8 character in canonical mode (for exampl= e, when cat > file is run on the shell command line) it will be two or more by= tes long. If you now hit the erase key (ie., backspace) only one byte will be deleted from the input buffer. For example, if you input =C3=A4=C3=BC and h= it backspace, the input buffer will now contain two bytes of utf-8 code for =C3=A4 and th= e first byte of the utf-8 code for =C3=BC, for a total of three bytes, which are in= valid. The iutf8 flag tells the terminal that the input is in utf8 and that the er= ase key in canonical mode should erase all bytes of the rightmost character. FreeBSD should support iutf8 so that canonical mode works fine with utf8 locales. --=20 You are receiving this mail because: You are the assignee for the bug.=
