Step to reproduce

• launching the command provided

Expected behavior

echo -e '1 abc\n2 dsg\n3 sadf\n4 dsf' | rofi -dmenu

Actual behavior

It seems like the japanese character cause rofi to freak out. As far as i am aware, i am not providing any "control" characters to the input, but i provide the command so anyone can tell.

Additional information

I've checked it against the latest stable as well as the new git, as i have seen there is something being done to fix some problem with emoji display.

Using wayland display server protocol

• No, I don't use the wayland display server protocol

I've checked if the issue exists in the latest stable release

• Yes, I have checked the problem exists in the latest stable version

Rofi does not do the font rendering, this is done by pango.
I am not sure what can be done about this.

It looks to me that rofipango uses another font to render when japanese characters are in the string.
This is pretty clear on my system:

Any pango/font expert have an idea how to avoid this?

[piko-piko]

Thank you for the clarification. I'll ask around unixporn discord if someone has any insight then.

[DaveDavenport]

If you find a solution, please report back so we can include it in the documentation.

Well, not really a solution, but at least a pointer for people who encounter this, it's a 5yo pango issue : https://gitlab.gnome.org/GNOME/pango/-/issues/353

[DaveDavenport]

That is a shame, guess there is no clear solution.
