https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220009 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 example, when cat > file is run on the shell command line) it will be two or more bytes 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 äü and hit backspace, the input buffer will now contain two bytes of utf-8 code for ä and the first byte of the utf-8 code for ü, for a total of three bytes, which are invalid. The iutf8 flag tells the terminal that the input is in utf8 and that the erase 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. -- You are receiving this mail because: You are the assignee for the bug.
