UTF-8 字符在新 Windows 终端的 Powershell 中显示为问号

Question

Japanese characters and Chinese characters, as well as emoji characters, are shown as?(question marks) in the Powershell window of the new Windows Terminal(installed from the Microsoft Store), and the Japanese and Chinese characters can be correctly shown in CMD window while the emoji characters still can not.

Microsoft claims that the new Windows Terminal supports the utf8 characters well but why can this happen? Are there any options to turn on the utf8 support?

As @vonPryz said, the Windows Terminal itself supports Unicode characters. If you want to handle Japanese characters in PowerShell, you have to change the codepage of your console to 932 .

Note that when you change the codepage of the console, first you have to run cmd.exe from PowerShell, then change the codepage in your console with chcp , and run powershell.exe . If you run chcp directly from PowerShell, it shows Japanese characters as ? .

Also, note that powershell.exe cannot handle emoji characters and causes System.Text.EncoderFallbackException in codepage 65001 because it uses surrogate-pair ( powershell.exe cannot handle surrogate pair correctly in codepage 65001).
