## Input from CLI

In CLI tool, all characters come as each of the bytes. All multibyte characters are split. In the middle of a line, a software should use an insertion of a new character but not a replacement.

## Yank

In the middle of a line, yank manipulation needs #byteinsert for multibyte editing.

Feature #14919: Add String#byteinsert

----------------------------------------
It's important for multibyte String editing. Unicode grapheme characters sometimes have plural code points. In text editing, software sometimes should add a new code point to an existing grapheme character. String#byteinsert is important for it.

I implemented by pure Ruby in my code.
