|
Fix techo handling of control and multibyte characters. |
|
|
|
ttecho compares signed char to '\x20'. Any character with code less then |
|
'\x20' is treated as control character. This way characters with MSB |
|
set to 1 are considered control characters too. |
|
|
|
Also this patch makes techo display DEL character as ^?. |
|
|
|
To reprocuce the bug, enable echo mode using printf '\e[12l', |
|
tthen type DEL character or any non-ASCII character. |
