well u have to rewrite the pattern \\p{ASCII}* to JS compatible
fashion

Hi,
I have a simple code that works correctly in development mode but
fails to run on production.
Basically, I need to check if the text entered by user contains only
ASCII characters. So, I do the following:
String s = getTextArea().getText();
if(s.matches(\\p{ASCII}*))
{
...}
else
{
// Some non ASCII characters found
}
On the production it always comes to the else section. I've tried it
with IE, FireFox and Chrome. The results are the same.
Any suggestions of how to fix this?

Re: String.matches() does not work with \p{ASCII}
hard to say, its up to the engine implementing regex, if you want to
check for ascii code of each character you gonnamake a loop
like
function isAscii(str){
for(i=0;istr.length;i++){
if(str[i]127)return false;
}
return true;
}
when making regex its like a touring machine which scans the character
applied to the pattern, so it also depends on a pattern how many chars
are scanned, and in your case you want to know if a character is in
ascii range, so anyway it has to scan each. there is one chance regex
is faster inthis case, if its implemented natively and not
interpreted.
the loop above has the advantage is has not to scan all of the chars,
in case its not ascii but returns after first non-ascii

Such as [\\u-\\u007F]*
try java.lang.Character to check or write in JSNI
small for-each testing if decimal value of char is greater than 127 is
faster than a regex evaluation
Are you sure? given that trimming blanks is faster with regexes
(str.replace(/^\s+/, ).replace(/\s+$/, )), I tend to think that
regexes are really fast.

as you probably know, regex is belongs to that cases not fully
compatible between java and javascript, and in dev mode your GWT
engine uses real JDK therefore it works, whereas after compilation
your matches() is performed on the browser with its regex engne and it
fails.
