Multi-Byte Number Matching

Question

I need to match multibyte 0123456789 characters from Japanese using regex.

[0-9] in this case does not work. How can I get this regex? This is my first foray into multibyte string matching.

UPDATE

Matching a 4 digit string, e.g. year of birth, was successful with both UTF-8 and UTF-8 using the following regex

^([0-9]{4}||[\uFF10-\uFF19]{4})$

Answer 1

A regular expression equivalent to /[0-9]/ for these multibyte numbers in Javascript,

 /[\uff10-\uff19]/ 

Answer 2

 var str = '０１２３４５６７８９'; console.log( str.match(new RegExp('[０-９]', 'g')), str.match(/[\uff10-\uff19]/g) ); //returns ["０", "１", "２", "３", "４", "５", "６", "７", "８", "９"] both ways 

Be sure to save the .js file with the correct encoding (UTF-8) if you are using a non-episized version.
