Colored undercurl and underline on WSL2 / updated ConPTY

[lostl1ght]

Hello!

Is your feature request related to a problem? Please describe.
No colored underline support on WSL2.

Describe the solution you'd like
From my understanding this PR finally added colored underline support to ConPTY.
Can you, please, update bundled ConPTY or guide me through updating it myself?

Describe alternatives you've considered
Ssh'ing to WSL2 which is a different can of worms. :(

Additional context
Also, by the looks of it, the PR did not make into a release, so downloading OpenConsole.exe from release files does not work.
Additionally, maybe this PR can clarify some details.

I think I've figured it out.

I've followed build instructions here.
I've built Release x64 CascadiaPackage using Visual Studio 2022, put conpty.dll and OpenConsole.exe from bin/x64/Release into Wezterm's folder and it just worked™.

Building the entire solution may fail but only conpty.dll and OpenConsole.exe are needed.

The result:

Would this also work for curly underline support in native windows?

[lostl1ght]

Looks like it would not.

Powershell run from wezterm:

WSL:

@lostl1ght thanks for sharing! Is anything stopping you from updating the pre-built files at https://github.com/wez/wezterm/tree/6a58a5ce94f186884ec70a60b5afbd728521b1c5/assets/windows/conhost?

@lostl1ght could you share which commit did you use to build it? Im having trouble replicating your results.

For people who still follow this thread, the bundled copies of conpty.dll and OpenConsole.exe were both updated in e7fe7c0 to the version that ships with Windows Terminal 1.19.240130002.

Undercurl seems to now be working without issues in WezTerm nightly, as showcased in the following discussion:
