Multi-byte input does not work properly, causing the notation to not match the input, resulting in incorrect editing.

[Yuutakasan]

Copying and pasting the following characters into a form, and then typing or deleting half-width characters after the following characters causes a strange phenomenon.

It is hard to explain in words, but it seems that the middle of multi-byte characters are deleted, and single-byte characters that should have been deleted are still displayed.

ああ⇒ああ⇒ああaa

The following is the form just after copying and pasting. Normally, after pasting, the input position on the keyboard is supposed to be right after the pasted character, but since the input position is at the end of the multibyte character, it is behaving strangely at this point.

In Thai as well. If you try to copy and paste below, you will see cursor is far behind the sentence.

It's not properly supported in other languages yet.
