Can you translate the error, or is it invalid Chinese? I see some characters are mangled (e.g. "Debug" lacks the "D").

Could you confirm which is the bug / unexpected behavior you are experiencing?

• There is an error (in Chinese) when using the editor in Chinese. There is no error when using the editor in English.
• There is an error both when using the editor in English and in Chinese, but you do not expect the error message to be presented in Chinese and would prefer it to be always in English?

Whether I'm using a Chinese or English editor, some strange characters that look like Chinese decoding errors appear. I think maybe it's because my computer language is Chinese so the compilation information returned by MSBuild is also Chinese, then the Godot editor decodes it incorrectly and then shows the wrong characters.

@L2750558108 Can you reproduce this error when starting from the _console.exe version?

试试复制这些出错的文字，用这个网址http://www.mytju.com/classCode/tools/messyCodeRecover.asp 看看来源的编码方式和造成错误的编码？

Try copy this corrupt words and using this website, to determine what your computer default encoding (codepage) is, and what encoding methods cause this error?

Reproduce on Godot 4 beta 12 mono:

Seems Godot decodes GBK strings using UTF-8:

The console output seems follow Windows system display language (or default CodePage of the shell), when using godot in english, the error still happens:

Running chcp 65001 before using console.exe is not working.

If you select default Windows Display language to Simplified Chinese on the initial setup (OOBE) of Windows, the default codepage will be set to 936 (GBK), but in most case of software dev, we uses 65001 (UTF-8), that's the problem that cause the issue.
Japan 932, Korea 949, Chinese Taiwan 950 also uses their specific codepages, that might also cause issue similar to this.

We could consider forcing MSBuild into the same language as the editor.

FYI I am working on a change for MSBuild to use UTF 8 if it's running in the context where DOTNET_CLI_UI_LANGUAGE is set. Might fix this for you. dotnet/msbuild#8503
