Fixed Prompt display will be shifted after use dir to display a filename with Chinese. (v25.00.28 x64)

[keysound]

I think it might be a bug. Please reference the screenshot.

When I use dir to show the files in my folder, if one of the filenames contains Chinese, the prompt will be shifted after pressing any key. However, everything will return normal after runs cls.

Is this with TCC in a console window, or in a Take Command tab window?

What code page are you using?

What font are you using?

What version of Windows are you running?

If you detach the tab, does the console window show the same thing?

And are those single-width or double-width characters?

The issue can't be reproduced after detaching the tab. I'm not sure what is the width of characters but I can paste the filename for your reference.

Fixed in 26.0.36 (only affects DBCS code pages).

 

[keysound]

Will you apply the fix to v25?

 

[rconn]

Possibly. The fix will be much more complicated in v25 (the relevant code in v26 had already been rewritten for UTF16 / UTF8), so v25 won't get a patch immediately.

 

[keysound]

Okay, I can understand. But I reported the bug with the subject that specificated a version, v25, and currently only v26 fixed. Changed the status to "fixed" might misleading others that v25 already fixed. Just my two cents.

 

[rconn]

I've uploaded a new v25 build (25.0.29) that includes a fix for this and a couple of Windows bugs that were fixed in v26.

Rex,

I still can reproduce the issue on 25.00.29 x64 but the behavior is a little changed. The promprt will back to normal state after typing some commands.

 

[keysound]

If I run "dir" rapidly, the screen will become this:

 

[rconn]

Try it with build 30 (already uploaded).

 

[keysound]

The problem still there.

 

[rconn]

Not reproducible here with build 30. What codepage are you using?

 

[keysound]

Okay, the settings to reproduce symptom is changed. The display is okay when code page is 950 but failed on 437.

 

[AnrDaemon]

Use code page 65001. It's year 2020 already.

 

[keysound]

The issue still there even changed code page to 65001:

WAD - the workaround is only for codepages 932-950. It has a noticeable effect on performance, so TCMD only checks for double-wide characters if you're using a DBCS codepage.
