Remove non-ASCII characters from String in Java

Question

I have a URI that contains non-ASCII characters like :

http://www.abc.de/qq/qq.ww?MIval=typo3_bsl_int_Smtliste&p_smtbez=Schmalbl�ttrigeSomerzischeruchtanb

How can I remove "�" from this URI

Answer 1

I'm guessing that the source of the URL is more at fault. Perhaps you're fixing the wrong problem? Removing "strange" characters from a URI might give it an entirely different meaning.

With that said, you may be able to remove all of the non-ASCII characters with a simple string replacement:

String fixed = original.replaceAll("[^\\x20-\\x7e]", "");

Or you can extend that to all non-four-byte-UTF-8 characters if that doesn't cover the "�" character:

String fixed = original.replaceAll("[^\\u0000-\\uFFFF]", "");

Answer 2

yourstring=yourstring.replaceAll("[^\\p{ASCII}]", "");
