A couple of things would be helpful:

1. What is the value of PS1?

2. Can you provide a filename or pathname containing Chinese characters I
can use to try and reproduce the issue?

hello,

Thanks. What is your locale? The output of running `locale' should be
sufficient.

[Chet Ramey]

Can you reproduce the bug?

I believe this is fixed in bash-5.0-alpha. If you would like, you can
download that from the GNU git repository on savannah.gnu.org:

http://git.savannah.gnu.org/cgit/bash.git/snapshot/bash-5.0-alpha.tar.gz

or the current development snapshot

http://git.savannah.gnu.org/cgit/bash.git/snapshot/bash-c2ccaa219a3e45be433b5ff797ce0331d9edfe43.tar.gz

I tried bash 5.0 alhpa, This bug is not fixed, but even worse.

Interesting. I can't reproduce it at all using bash-5.0, Mac OS X,
and Terminal.

I use ubuntu18.04, tried bash 5.0 alpha, maybe the vte's version is not the
same?
Do I need update vte library?

No idea. I'll look at it some more. (And it seems to work fine using iTerm
as well, for what that's worth.)

I tried the current devel branch head on Debian 9 (a random VM I had around,
so I'm not sure about the patch level) and it seemed to display fine.

The vte developer says I don't need to upgrade vte library.
"VTE's emulation behavior hasn't changed recently in ways that could be
relevant here. Seems to me you're on Ubuntu 18.04 which ships the latest
stable VTE anyway."
So, I don't know what to do now...

I'll take a look at Ubuntu when I get a chance.

I'm not sure what to tell you.
