[Ken VanDine]

The input method used by GTK to select emojis shows broken unicode characters. Installing the following packages fixes it:

[Jean-Baptiste Lallement (jibel)]

fonts-liberation2 and fonts-opensymbol are installed on minimal by dependency from libreoffice but on the removal list.
fonts-noto-color-emoji is explicitly on the removal list for minimal.

Seeding these 3 fonts in minimal would add 8MB to the minimal installation but not increase the size of the ISO because they are already seeded there.
