How can my input accept only numbers written in latin charset or Japanese: I googled it but just can get result of latin charset only, not utf-8 supported.

Answer 1

Use HTML5 pattern validation

<input pattern="[\d\uff10-\uff19]*" />

\d matches a digit (character in the 0-9 range).

\uff10-\uff19 matches a character in the ０-９ range.

* means zero or more times.
