Version Information

Cmder version: 1.3.21
Operating system: win11

Description of the issue

When running a Python CLI program 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
looks fine in powershell:

wired in cmder:

The difference is Windows Terminal vs ConEmu.

Powershell isn't related to this.

Also, probably if you run chcp 65001 that might resolve the issue.

Code page 936 has a collection of characters that it defines as "ambiguous width". Some things treat them as 1 cell wide, and some things treat them as 2 cells wide. Setting the terminal to use code page to UTF8 (by running chcp 65001) gets out of that mode, and then the character widths are unambiguous.

You might be able to try a different Chinese font in ConEmu, or a different font size. It looks like the Chinese font is different than in Windows Terminal, or at least a slightly different size.

But this isn't a Cmder issue, it's a ConEmu issue. Try going to the ConEmu repo and searching issues there, or opening an issue there.
