What font am I missing? #913

Closed Aster89 closed 5 years ago

Aster89 commented 5 years ago

I just have a simple question, not a bug report, but I still fill the full report.

Version

Version: 1.5.2

Configuration

Output of rofi -help)

Launch Command

rofi -combi-modi window#drun#ssh -font "hack 20" -show combi

Steps to reproduce

Open rofi, normally, and look at the entries relative to already opened applications

What behaviour you see

I see I miss some font, but I don't know how to determine which one(s). Screen

What behaviour you expect to see

The font well reproduced, so I'd like to receive help in discovering what font I should install.

DaveDavenport commented 5 years ago

That looks more like something is corrupting the window/desktop name.

0020 is a control character?

Aster89 commented 5 years ago

0020? The unicode space?

DaveDavenport commented 5 years ago

can you post out.txt of:

xprop  -root  > out.txt
DaveDavenport commented 5 years ago

0020? The unicode space?

aah silly me, read it as decimal :smile:

DaveDavenport commented 5 years ago

anyway, check fontconfig setup for fallback fonts. I am not too familiar with it.

0020 is a control character?

I'd answer Yes, it is, that's what wikipedia says, but I suspect you're question wants a different answer :nerd_face:

Aster89 commented 5 years ago

anyway, check fontconfig setup for fallback fonts. I am not too familiar with it.

So how should I preceed?

A-Louarn commented 5 years ago

Hi, I have the exact same problem. I too use i3 with emojis / fontawesome characters in workspace names, and some of them are padded with \u0020 characters.

I feel like this is not a font issue (since i3 and termite show absolutely no \u0020 chars, and Rofi shows the correct symbol), but more an issue with how Rofi handles emoji / fontawesome characters (in particular the spaces after those characters)

If it helps, here is a screenshot and my xprop -root:

Does: echo -e "1:,\u0020|" | rofi -dmenu Show it correctly. (It does for me btw.).

A-Louarn commented 5 years ago

Yes, when the comma is set directly after the firefox character, everything is shown correctly. But if the character following the firefox character is a space, the glitch appears:

$ echo -e "1:,\u0020|" | rofi -dmenu 2019-02-25_152524_5040x1920

$ echo -e "1:\u0020|" | rofi -dmenu 2019-02-25_152615_5040x1920

$ echo -e "1: \u0020|" | rofi -dmenu 2019-02-25_152701_5040x1920

Aster89 commented 5 years ago

@TheMrNomis , I can confir this behavior.

A-Louarn commented 5 years ago

By the way, I made a few tests, and the same bug is appearing with any unicode whitespace (as per https://www.fileformat.info/info/unicode/category/Zs/list.htm ) It also appears when using a zero-width space, albeit the zero-width space itself is not displayed (but the following spaces have the weird "missing character" box)

$ echo -e "1:\u200B\u0020|" | rofi -dmenu 2019-02-25_154121_5040x1920

The only exception is the Ideographic space (\u3000) which is displayed normally (a big space), and the following spaces are displayed correctly. EDIT: $ echo -e "1:\u3000\u0020|" | rofi -dmenu 2019-02-25_154437_5040x1920

DaveDavenport commented 5 years ago

with my font I cannot reproduce it. fun.

Can you try in another pango based application , like gedit (with this font).

A-Louarn commented 5 years ago

Yes, same glitch. May be a pango thing, then. 2019-02-25_154833_5040x1920

DaveDavenport commented 5 years ago

looks like it. I think I actually reported this one before a long time ago.

DaveDavenport commented 5 years ago

https://bugzilla.gnome.org/show_bug.cgi?id=780068 https://bugzilla.gnome.org/show_bug.cgi?id=775202 (also reported https://github.com/Anachron/i3blocks/issues/53)

cannot find the bugreported I commented on in the past.

A-Louarn commented 5 years ago

Yes, that's exactly the same bug. Apparently it's because font-awesome does not offer an ascii space. On arch, switching from ttf-font-awesome to otf-font-awesome worked around this bug.

I think there is nothing that can be done at the Rofi level, and this request could be closed. Thanks !
