Support cyrillic character set

What would you like to add

Support of the cyrillic character set inside the actual ESP32 devices.

How this relates to Home Assistant

Home Assistant itself is supports full unicode charactersets and the Tessera editor also shows the correct characters but the actual ESP32 device seems not supporting this character set.

Pictures, mockups, or examples

Tessera editor shows... (the cyrillic word for "media")

ESP32 devices shows... (just shows "squares" because of missing glyphs)
