  • Version: 10.0.0 nightly 2018 01 14–16
  • Platform: Windows 7 x64, cmd.exe shell
  • Subsystem: repl

Steps to reproduce:

  1. download a Windows nightly from 2018 01 14 up to 2018 01 16.
  2. Start REPL session.
  3. Evaluate some last commands from the history with UP+ENTER keys.

Anomalies:

  1. Strange prompt symbols / output wrappings (ANSI escape codes?).
  2. These symbols are preserved and added with each UP key press.
  3. The output is decolorized.
