I have installed "Helvetica" in Ubuntu, but it have a bug with Google Chrome. Well, I removed it from
~/.fonts/ folder, but the problem persist.
The problem is that Chrome (and also any Electron app, like Wmail) render the Helvetica font without spaces and with blue circle around the number, as you can see in the previous screenshot.
Here are two screenshot of the problem
And after I replaced the font with Arial, this was the result
There is any other font folder or any font cache that Ubuntu store for Google Chrome?
