After updating webmin to 2.401, some Japanese characters were displayed strangely. I had no choice but to downgrade to 2.305.

Hello,

Thanks for the heads-up! Unfortunately, this was a bug, but it has now been fixed and will be addressed in the upcoming minor release of Webmin 2.402. However, if you don’t want to wait, you can apply the patch now.

Thank you.
I am waiting to bug fix ver2.402.
