Description

When running a full_screen app 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. By the way, i have ran chcp 65001(use utf8) in cmder

looks fine in powershell:
1
wired in cmder:
2

Research direction

Start by reproducing the full_screen app with Chinese characters in cmder after setting chcp 65001, then compare the rendering with PowerShell. Done means Chinese-character lines no longer produce color blocks or extend beyond their expected length in cmder.
