regex with accents

[albert]

Hi,

I can't get the characters with accents in a regex. This is my code :
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
var MyText1 = "éléphant1" ;
var MyText2 = "elephant1" ;
var MyReg = /^[\w]+$/ ;

if(MyReg.test(M yText1))
alert(MyText1 + " is OK") ;
else
alert(MyText1 + " is not valid") ;


if(MyReg.test(M yText2))
alert(MyText2 + " is OK") ;
else
alert(MyText2 + " is not valid") ;
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Here's what I get :
éléphant1 is not valid
elephant1 is OK

I'd like éléphant1 to be OK, but I can't.
Can you help me ?

Thanks in advance,

Albert

ECMA262 15.10.2.12 defines \w as being equivalent to the character class
[0-1A-za-z_]. The w suggests word, but that is deceptive. Support for
internationaliz ation in JavaScript's RegExp is virtually nonexistent.

You need to define your own character class.

var MyReg = /^[\wáéíóäëiöúàèìì ù]+$/i;

Depending on your local requirements.

pb? [please no sms-language on usenet]

Why should it be easy?

pb = problem (sorry, I thought it was obvious).

I've never said it should be easy. Don't waste time to answer here...

Well I tried a simple word in Arabic with the following regex :

^[\w]+$

still, the "test" function always returned false. Do you have any good
working example about it ?


thx, oops, soory I meant "Thanks" ;-)

Not to me. Usenet has it's own limited set of abbreviations.
If any Pb perhaps would be lead.

Would you allow for figures 0-9?
Otherwise this is better for simple Latin chars:

/^[a-z]+$/i

still, the "test" function always returned false.

I showed you how to do that with accents,
did you understand the regex?

Why would Arabic characters match
where accented characters do not?

Do you have any good
working example about it ?

I am not into working examples, but will gve you a hint.

Arabic should work the same as accented ones:

/^[a-z\u0600-\u06ff]+$/

[http://unicode.org/charts/PDF/U0600.pdf]

Not knowing Arabic I cannot test that.
