ES regex does not recognise umlauts etc...

Friends of regular expressions!

I want to check for valid (special) variable names and use

\w

for word characters. This does not find characters such as ä - or any other none-ASCI character.

My test script is this:

var toTest = [], j, n;    toTest.push("#Apple");                            // true    toTest.push("#Apfel, #apple, #Gurkensalateska");  // true    toTest.push("#t_27Apples");                       // true    toTest.push("#côté");                             // false    toTest.push("#Grüne_5Äpfel");                     // false    toTest.push("#Äpfel");                            // false

n = toTest.length;
for (j=0; j < n; j++) {  $.writeln(ContainsVariable (toTest[j]), " ", toTest[j]);
}

function ContainsVariable (text) {
var re_variable= /(^#[\w][\d_\w]*)(, +)?/,
    indexOfChar, character, lSkip, kText;  for(indexOfChar = 0; character = text[indexOfChar]; indexOfChar++) {    kText = text.substring(indexOfChar); // rest of the statement    sFound = kText.match(re_variable);    if (sFound != null) {      lSkip = sFound[0].length;      indexOfChar = indexOfChar + lSkip -1;      continue;    }    return false;  }  return true;
}

Any ideas how to get valid results for non-english variable names?

There seem to be other shortcomings also: indesign-scripting-forum-roundup-7#hd4sb3.

I have not found any documation about the regex-flavour of ES. Isn't there any?
