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:

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.

I have set the environment like this,but noting changes

tried run chcp 65001, doesn't resolve this issue :(

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.
