@dzmitry-lahoda this has been proposed earlier https://github.com/near/borsh-rs/pull/248/files .
Does it look like what is required of this issue resolution?

Indded, sorry. Was too Rust centric.

@dj8yfo btw schema for chars, not serde for chars.

#247 (comment)

i more of need metadata for chars, okey to have variable lengths.

i build something like reflection/diff of data storage of borsh.

well, rust stdlib has an explanation that char is Unicode Scalar Value, serializing it as 21 bits or 4 bytes would be an implementation detail; 4 bytes would be a lot simpler
