Full kaomoji support

**Is your feature request related to a problem? Please describe.**
The font used for the faces only supports a limited selection of characters unlike traditional kaomoji
unsupported characters just show up as squares

**Describe the solution you'd like**
add the full range of kaomoji characters

No file or test is named. Start by locating the font and rendering entry point used for the faces, then identify how unsupported kaomoji characters become squares. Define the intended character coverage and verify representative traditional kaomoji render without replacement squares.
