Character and word counter use one ending for counting both in words and characters.
In ukrainian it have couple endings.
Two examples to make understand how it should be:
words:
“1 слово, 2-4 слова, 5-20 слів, 21 слово, 22-24 слова, 25-30 слів, 31 слово, 32-34 слова, 35-40 слів, … 121 слово, …”
characters:
“1 символ, 2-4 символи, 5-20 символів, 21 символ, 22-24 символа, 25-30 символів, 31 символ, 32-34 символи, 35-40 символів, … 121 символ, …”
but you can make it simpler, just mirror sentence:
“символів: [any number]” and “слів: [any number]”
otherwise it weird and confusing
