Problem description

When running a Python CLI app based on prompt_toolkit in cmder, there are strange color blocks in the UI. It appears to be a problem with Chinese character parsing, as lines containing Chinese characters render with color blocks exceeding their expected length. However, this issue does not occur in PowerShell

Actual results

Expected results

result in the [RealConsole] by Ctrl-Win-Alt-Space

Any suggestions? I need help :(

By unchecking the TrueColor mode, I solved the problem. It can also be solved by setting the bg color as ANSI color.
