Description
Windows 10, Windows Terminal, Version: 1.3.2651.0
Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]
Windows Terminal version (if applicable):
Any other software?
I use
-- SetConsoleMode(hStdin, ENABLE_WINDOW_INPUT | ENABLE_LVB_GRID_WORLDWIDE )
-- I do "| COMMON_LVB_UNDERSCORE' on the attributes of CHAR_INFO 'line'
-- WriteConsoleOutput(... line );
I am 95% sure the rest of the code is valid -- because I can do colors, etc.
Expected behavior
-- characters should be underlined.
Actual behavior
-- no underline

Research direction
Start by reproducing the reported sequence using SetConsoleMode, COMMON_LVB_UNDERSCORE, and WriteConsoleOutput through ConPTY. Compare the handling of underline, overline, and left/right gridline attributes, then verify that the corresponding characters render with those attributes in Windows Terminal.
