In Chromium based web browsers, we have problems with entering double-byte characters.

Once I have confirmed the letters, the letters are always entered twice in a row.
When I confirm the character input, the letters are always input twice consecutively.
For 2-byte character input, there are two steps of checking the character input and confirming the input.

Example: *I intentionally write in the alphabet.

WATASHIHA MANGAGA SUKIDESU.
*I like cartoons.
*私は漫画が好きです。

WATASHIHAWATASHIHA
MANGAGAMANGAGA
SUKIDESUSUKIDESU

私は私は
漫画が漫画が
好きです好きです

One clause is doubled as above.


If this is a smartphone(Android/iOS) it is not possible to enter text fatally.
I input "WATASHIHA" and confirm the letters, only "WA" is reflected. That is the first word.
*INPUT "私は". Only "私".
