I found a solution for this problem. Try this:

sudo apt install ttf-mscorefonts-installer
sudo fc-cache -f -v

The problem come from the fonts. In Odoo12, default font for Bootstrap 4 is Noto Color Emoji and because of that, when you generate a report, wkhtmltopdf will crash. After this package you will have this font. If problem persist, try to install also - http://download.odoo.com/fonts/Roboto-Regular.ttf Tell me if it works. You can track this issue right here - https://github.com/odoo/odoo/issues/27487

Wonderful ..Thank you very much :) – Nebil Aydi Nov 30 '18 at 07:53
For me, the MS fonts package brought more trouble than its worth. Various issues raised later, related to broken repositories etc. Instead installing MS fonts package and dealing with its licencing and other problems, **you could simply just install Roboto**. One click install and no more problems. – ruuter May 13 '19 at 12:06
