Invisible = sign

[hauleth]

I am using Terminal GNOME 3.16.2 and when I am trying to use Fira Code 1.102 = sign (0x3d) is invisible.

ping @tonsky

[tonsky]

Yeah, guys, I don’t have Gnome terminal to test. Have you considered a possibility there’s a bug in terminal itself? Because Fira Code works really well everywhere else

[rahilwazir]

@tonsky I have tested with several other fonts like

• Hack
• Ubuntu Mono
• Source Code Pro
• Andale
• DejaVu
• Droid Sans Mono

They are all working fine.

Any specific sequence where = disappears?

@tonsky No, just type = anywhere in any sequence, it just displays as invisible.

Gnome Terminal doesn't support ligatures so you should just use Fira Mono with Gnome Terminal.

[hauleth]

I have been using FiraCode as it also provides other smaller or bigger changes to the font other than ligatures (ex. Powerline symbols)

Broken for me in phpstorm as well.

This is supposed to be

= == ===
- -- ---
!= !==

EDIT: Seems to be related to font size, this is at size 12 instead of 14:

[MadcapJake]

@KaelWD please open a separate issue, PHPStorm is a completely different implementation of ligatures to Gnome Terminal's (also your issue is different just in general).

[rahilwazir]

@KaelWD I'm confused?! Whats the issue?

[KaelWD]

@MadcapJake Sorry, will do. It just seemed related because it's a similar problem (part or all of the = character not rendering).

@rahilwazir At size 14 (img 1), = and == display as a short and long dash respectively. At size 12 the spacing between the lines is off, most visible in !==.

[tonsky]

@KaelWD report to https://youtrack.jetbrains.com/issue/IDEA-127539

@hauleth @rahilwazir is it broken in Gnome terminal only or in all other linux apps as well. What font rendering setting are you using system-wide?

[rahilwazir]

@tonsky Only in Gnome Terminal.

Hinting: Maximum/Full
Antialiasing: RGBA

It's also broken in Terminator, the '=' sign is gone and all other ligatures are messed up.

This is an issue with libvte (the terminal library gnome-terminal, terminator and other terms use).

See here: https://bugzilla.gnome.org/show_bug.cgi?id=584160

[meskarune]

Also happens in termite terminal, which also uses libvte. So I just wanted to confirm.

[concatime]

Any news? It seems that we're kinda stuck.
(Also had the issue with the = inside Termite, no matter which font is used)

[tonsky]

was this reported to libvte? maybe you should ask them to fix it?

[klummy]

I think this is likely related to #247 since Gnome Terminal doesn't support ligatures

[Albert221]

I've also experienced this issue. I think that using Fira Mono as terminal font is a good way to avoid this problem, but this should be definitely fixed

[kdrag0n]

Having this issue in every libvte terminal I've tried as well. Fira Mono works fine. Not only is = broken, </a> is broken and displays /b with the <=> overlapping it. Examples:
</b>

<a href="test"> <a></b>

FWIW, I saw weird char replacement issues in GNOME Terminal 3.28.2 using VTE 0.52.2 (on fod, in only some Fira Code variants:

• only in Fira Code Retina, | U+007C VERTICAL LINE displayed exactly as ^
  

• only in Fira Code Bold Italic, | U+007C VERTICAL LINE displayed as &, and some other chars +^ displayed as ⌡...
  

But after playing with antialising settings back and forth, things changed (eg. now retina is good but bold and italic bold show | as &), so I guess these are not specifically these fonts and chars, but some kind of font cache issues... (?)

[imflash217]

Same issue even now on some ubuntu installations (on both Guake, Gnome Terminal).
Fira Mono works fine though.
