Unexpected ANSI sequence behavior in CMD.exe

Question

![208435-image.png][1] [1]: /api/attachments/208435-image.png?platform=QnA On the left you can see the result of an underline text attribute being applied to the console screen in Windows Terminal, and a message being displayed. On the right you can see the same operation done on cmd.exe. Both terminal windows were resized, however the display on CMD is messed up. It seems like the attributes were applied everywhere. Why is this happening? How do I avoid this behavior on the console? The application (tat) is using ANSI sequences with ENABLE_VIRTUAL_TERMINAL_PROCESSING enabled to affect these attributes.

Answer 1

VT emulation on Windows is very bad.
My advise - not to bother too much.

PS Graphics rendition is a responsibility of "ESC [ <n> m SGR" command.
