ConEmu can't represent unicode characters properly (e.g. emojis)

Version Information

Cmder version: 1.3.25.328
Operating system: Win 11 25H2

Cmder Edition

Cmder Full (with Git)

Description of the issue

I have some Unicode characters missing/misrepresented in the terminal, see below, compared to the Windows terminal

I know that this is dependent on ConEmu.
Since the latter looks to be a dead project (here on Github), but cmder uses it, this is the only place where I can report this issue.
Ultimately, the bug is that cmder relies on a dead project.

How to reproduce

1. Take the file icons.example from the lf project, still on Github
2. Execute sed -n -e "/tex/p" -e "/\.r/p" icons.example to expose some of the missing characters
3. The same command in Windows terminal (or in a Unicode editor) will show the correct characters

Additional context

Note that missing characters also generate misprints in width, misaligning text.

Checklist

• I have read the documentation.
• I have searched for similar issues and found none that describe my issue.
• I have reproduced the issue on the latest version of Cmder.
• I am certain my issues are not related to ConEmu, Clink, or other third-party tools that Cmder uses.

Start by reproducing the issue with the linked lf icons.example file and the provided sed command, then compare the output with Windows Terminal. Investigate how Cmder relies on ConEmu for Unicode rendering and width calculation; done means the affected characters display correctly without misaligning surrounding text.
