The writing is crooked and childish, partly owing to the fact that it's scratched with a stylus on tree bark, but to anyone who reads Russian or another adjacent Slavic language, pieces of the text are immediately comprehensible. It's even easier to make progress if you've seen Church Slavonic writing and text abbreviations, which are ubiquitous on religious imagery present in basically every Eastern Orthodox church throughout Russia and other countries with Orthodox churches.
The "I am a beast" letter says the following:
(text box) ПОКОЛОNО ѿ ОNΘΗМА КО ДАNΗЛѢ
(free-floating) Ѧ ЗВѢРЕ
After accounting for the mixture of letters from the modern Russian alphabet, the Greek alphabet, antiquated Slavic letters like Ѣ and Ѧ, and the unfamiliar orthographic abbreviation ѿ (which is a tau Τ planted on top of an omega ω), the first inscriptions say, using modernized orthography and syntax, "поклон от онфима к даниле" and "я зверь," or "greetings from Onfim to Danilo" and "I am a beast."
The remaining inscriptions are an exercise for the reader.
I believe, U+0415 ("E") is a valid character to use there. Sadly, there's no way to denote that the text is in Old Slavonic and should use different script so this "E" would be rendered visually similar to "Є".
While Unicode code points typically correspond to graphemes, that's not always true. Similar issues exist with Chinese, Japanese and Korean languages, as Unicode (see https://en.wikipedia.org/wiki/Han_unification#Graphemes_vers... - it has an example with Latin small letter "a")
Like, all of them? At least, "words comprehensible to a Russian-speaker".
>Does Russian alphabet have Є letter?
Ukrainian still does. It's closer to the Old Church Slavonic. And the Ѣ was only dropped 100 years ago by the commies.
Regardless, nobody is saying that the beresty are modern Russian, just that it's in a Slavic language (and one comprehensible to modern-day Russian speakers). What's your point, exactly?
