Windows TUI prints raw ANSI escape sequences instead of rendering (Windows Terminal, PowerShell, cmd)

Version

Kimi Code CLI 0.26.0

Platform

• Windows 11
• Reproduced in:
  • Windows Terminal + PowerShell 7
  • Windows Terminal + cmd
  • Warp + PowerShell 7
• Install path: %USERPROFILE%\.kimi-code\bin\kimi.exe

What happens

Running kimi dumps the whole TUI as literal escape text. Colors, box drawing, cursor control, etc. never render. The UI is unusable.

You get stuff like:

←[?2026h ←[0m←]8;;←[?2026l←[?25l←[?2004h←[>7u←[?u
←[2K ←[38;2;79;168;255m╭────...
←[2K ←[38;2;79;168;255m│←[39m  Welcome to Kimi Code!
...
←[38;2;224;224;224mK2.7 Coding thinking←[39m

So sequences are being written, but nothing is interpreting them. The ←[ form is the usual Windows "ESC shown as text" look.

Expected

Normal interactive TUI: welcome panel, prompt, colors, no visible escape codes.

Steps

1. Install Kimi Code CLI 0.26.0 on Windows.
2. Open Windows Terminal.
3. Run in PowerShell: kimi
4. Same with cmd.exe: kimi
5. Observe raw escape sequences instead of a rendered UI.

What I already tried

• Confirmed it is not Warp-only. Same failure in Windows Terminal with PowerShell and cmd.
• Set HKCU\Console\VirtualTerminalLevel = 1
• Set user env COLORTERM=truecolor and FORCE_COLOR=3
• Forced VT processing on the console handle before launch
• None of that fixed it

Notes

• Looks like a Windows console / VT handling problem in the 0.26.0 TUI path, not a single terminal emulator bug.
• Visible control sequences include truecolor SGR, synchronized output (?2026h), OSC 8 hyperlinks, and Kitty keyboard protocol bits (>7u, ?u).
• Non-TUI paths are fine as a workaround (kimi web, kimi -p "...").

Screenshot

Start by reproducing the 0.26.0 TUI path with kimi in Windows Terminal using both PowerShell and cmd, then inspect the Windows console and terminal-output initialization. Compare behavior with the non-TUI commands and verify that the interactive UI renders colors, box drawing, cursor control, and hyperlinks without visible escape sequences.
