Hi,  
The underscore character appears as a white space in my Juno’s REPL.  
Do you have similar experience ?

Works fine for me with v1.0.2.

Thank you. I also run v1.0.2 and an up to date juno… (1.34.0 atom and 0.2.0 uber-juno).  
On the following screen shot I wrote toto\_4 both in the editor and in the REPL:

I have an older atom: 1.33.1 for Atom and uber-juno 0.2.0  
(But after checking them, somehow I messed up my Atom (juno) and don’t have time to resolve it now.)

This is a known upstream issue with the terminal library used by Juno:

Sorry. I have looked for underscore on discourse but not on the Juno’s issues.  
FWIW the problem disappears when I check the FallBack Renderer Console option.

How did you fix it exactly? I’ve been having that issue for a while and will like to figure it out.

I clicked `Julia` button in the top menu  
 → `Settings`  
 → `Console Options` (you have to scroll down a bit)  
 → validate the `Fallback Renderer` button  
It solved the problem in my case.

I changed to a different font.

Which one worked? Deja Vu Sans Mono doesn’t display the underscore and cuts the lower part of j and g.

The `FallBack Renderer` did not solve the problem ?

The `Fallback Renderer` option should definitely be a workaround for this issue.

Source Code Pro works fine for me.

Deja Vu Sans Mono has very low-hanging underscores, for some reason.

I finally settled for monospace. The _Fallback renderer_ option alone didn’t fix it. But thanks for bringing it up in Discourse, because it was something that I was meaning to fix.

I have the same problem. The fallback renderer does not help.

> [@LaurentPlagne](#):

There is no Editor section under Julia-\>Settings in my installation.

I have tried:

- Latest Juno with atom 1.37 official Linux binary on Oracle Enterprise Linux 7.
- Latest Juno with atom 1.40 from flatpak on Ubuntu 18.04.

With the first one, I also tried installing the fonts package and changing the font: it changes the editor font but not the console font.

You have to go the `julia-language` package settings, I believe. That’s where you can change the font, which I what I ended up doing.

Thank you for your reply.  
Unfortunately I do not find a way to change the fonts in the settings of language-julia or that of julia-client.
