Regular Expression for Japanese characters

I am doing internationalization in Struts. I want to write Javascript validation for Japanese and English users. I know regular expression for English but not for Japanese users. Is it possible to write one regular expression for both the users which validate on the b开发者_如何学Goasis of Unicode?

Please help me.

Here is a regular expression that can be used to match all English alphanumeric characters, Japanese katakana, hiragana, multibytes of alphanumerics (hankaku and zenkaku), and dashes:

/[一-龠]+|[ぁ-ゔ]+|[ァ-ヴー]+|[a-zA-Z0-9]+|[ａ-ｚＡ-Ｚ０-９]+|[々〆〤ヶ]+/u

You can edit it to fit your needs, but notice the "u" flag at the end.

Provided your text editor and programming language support Unicode, you should be able to enter Japanese characters as literal strings. Things like [A-X] ranges will probably not translate very well in general.

What kind of text are you trying to validate?

What language are the regular experssions in? Perl-compatible, POSIX, or something else?
