This problem is due to the fact that the character length is not calculated correctly. UTF-8 encoding, the length of the character may be 1~4 bytes. So the cursor is not positioned correctly.

Run
Install-Module PSReadLine -AllowPrerelease -Force -AllowClobberto get 2.0.0-beta1 with the fix.PowerShell 6.1 will soon pull this version as well, see #5759
If you're running on Linux, you might need to rename the install directory to fix the case, I think it gets installed with
PSReadlineinstead ofPSReadLine. I'm looking in to how that can be fixed.rkeithhill commentedon Jan 11, 2018
Ah, then ignore my comment - PowerShell/PSReadLine#555 (comment), Ah yup, this command
sudo mv /usr/local/share/powershell/Modules/PSReadline/ /usr/local/share/powershell/Modules/PSReadLine/fixed it for me.lzybkr commentedon Jan 11, 2018
Keith Hill (@rkeithhill) and anyone else - the PSGallery team have kindly updated the back end, so PSReadLine 2.0 should now install correctly on Linux/Mac w/o needing to rename the directory.

chuanjiao10 - that's definitely a bug, go ahead and open an issue in the PSReadLine repo.
