Normal Cyrillic, but with additional characters. This is required to display some letters in the Ukrainian alphabet

I wouldn't want to force everyone to use the cyrillic-extended font, as not everyone needs it and it limits the number of fonts to use. So the best idea would be to add the option to download your font

I will try to add special character support, like emojis, in greetify itself, so it will be fine for those using the default font, and also add custom font support.
