@hxse Thanks for reporting. Is this specific to windows terminal or you can reproduce it on different terminals as well? This may likely be terminal or a tcell issue. Also can you copy the names of those files here as text so maybe we can try reproducing?

[hxse]

@gokcehan I only know that Windows is like this because I only have Windows.
On windows: "windows terminal", "cmd.exe", "Windows PowerShell", they all have this bug
Test cjk str:

I had a similar problem with Japanese fonts. When LF displays the Japanese file, the rendering was weird and finally the console crashed. However, when I turned on "legacy console" in the command prompt options, it rendered fine.

Unfortunately I no longer get to choose my favorite font in legacy console(probably can be changed in regedit), but for the moment it works fine.

@mshungo Thanks for the workaround. It's unfortunate that I don't know how to solve some of these terminal issues. I have now created a Troubleshoot wiki page so such workarounds would not be buried in the issues. I have tried adding this to the page. Feel free to add more information there if you like.

Emmm this is a really annoying bug. Is there any way to prevent the preview of CJK? by configuring the previewer or something.

[gokcehan]

@zcysxy That might be possible if there's a way to tell if a file has CJK characters from within the script set for previewer.

Hi, @hxse, I found that you have closed this issue. Is there any idea for a solution for this?

[gokcehan]

We can reopen this issue to track it but I don't think there is much we can do about this on our side. From what I understand from discussions, I suspect this is a tcell issue as it uses a different API for unix and windows. I found junegunn/fzf#2715 reported in fzf repository which might be related to this issue. Unfortunately, I haven't found anything related reported in tcell repository. If anyone wants to see this issue fixed, it might be a good idea to reproduce this issue with a toy example for tcell and report the bug. If the issue is solved, we can simply bump our tcell version in lf to include the fix on our side.

@gokcehan yeah, I agree with you, and I found a related issue in microsoft/terminal#12479 and it is now assigned to a contributor of that repo. Maybe we will get a conclusion soon XD.

you can reset key l && h,and use reload command;
I use powershell in windows11. and now it's very nice.
eg:

# lfrc

map l 
map h

map l :open; reload
map h :updir; reload

[ayuayue]

and set j,k to redraw

# lfrc
map k
map j

map k :up; redraw
map j :down; redraw

and set j,k to redraw

# lfrc
map k
map j

map k :up; redraw
map j :down; redraw

In WindowsTerminal with pwsh7, without these maps, chinese characters can be rendered sometimes (every movement has a chance to (dis)appear chars, weirdly), and even cannot highlight text preview properly.
After setting, chinese characters completely disappear 💀.
I have given up WindowsTerminal. Instead, WindTerm can render chinese chars (but sometimes misses the first char) and true color.
