Hi,

the following code fragment shows a simple alphanumeric character check
method, which checks if any char inside a passed string is alphanumeric. -
Java's "isLetterOrDigit(char)" method's behaviour from the string class
seems not to include whitespaces, punctuation chars like ".", the "@" sign
and german umlauts (�������) etc.

Isn't there some equivalent method available which provides something
similar to "isASCII", which looks for all chars from ...say... the extended
ASCII charater set or unicode set, so that all above mentioned chars will be
recognized?

....
 // check for a string only containing alphanumeric characters
    private boolean check_alphanumeric (String inputField)
    {
     char array[] = inputField.toCharArray();
     Character chr = new Character(' ');
     int i = 0;

     while (i < inputField.length()) {
      if (!chr.isLetterOrDigit (array[i]))
       return false;
      i++;
     }
     return true;
    }
...
