ok, the status bar one.

[ruizone]

In the case of many files, it is very troublesome to select this file.

The file name is not truncated and will cause the rename to fail.

[jarun]

what's your version of nnn?

Move the cursor up and down. The panel displays an error.

@ruizone the issue is wcswidth returns wrong length. It depends on locale. See the notes section:

NOTES         top
       The behavior of wcswidth() depends on the LC_CTYPE category of the
       current locale.

It seems Termux doesn't have locale support.

Please refer to termux/termux-packages#2796 (comment)

@fornwall does this still hold?

[jarun]

I also confirmed that this doesn't happen if I use a long file name with English characters only.

@jarun It's true that wcwidth() and related functions does not work on Android prior to Android 9.0.

However, Termux has a libandroid-support library adding that function that programs can link against. I've enabled that for nnn (in version 2.5-2 of the package), so it should now work.

@ruizone Run pkg up to update and test again!

@fornwall I have tested it and this is fixed now! Thank you so much!

[ruizone]

@fornwall The problem has been fixed very well. Thank you.
