converting String from UTF 8 to ascii format

[Amol Juvatkar]

hi all,
I have String in UTF8 format,
how can display it in ascii format.

Thanks,
JAmol

ASCII text and UTF-8 will look exactly the same (ASCII characters are stored using the one byte in UTF-8) regardless of which encoding they use.

You don't have a String in UTF-8 format. It's possible that you have an array of bytes that represents a String encoded using UTF-8, but Strings are raw Unicode characters and do not have an encoding. Was there another question that caused you to ask that? Perhaps it would be easier to answer the real question.

I think this link might help you:

e186. Converting Between Strings (Unicode) and Other Character Set Encodings

Althoug your conversion sound a bit strange, because US-ASCII is a subset of UTF-8, hence, some of the characters that you will convert from UTF-8 to US-ASCII may not have any representation in US-ASCII, and the ones which does were already part of the UTF-8.

Well, whatever, I hope this link helps.

hi,

real problem is ,
as per my requirement, I was trying to retrive user data, including password from LDAP using java APIs.
but password for known user is displayed in different format,
after going through link

http://www-304.ibm.com/jct09002c/isv/tech/faq/individual.jsp?oid=1:78875

it says userPassword attribute is returned in UTF-8 format. To use this attribute, you need to convert it from UTF-8 into ASCII.

hope you got my problem,

Thanks

Then you are getting a byte array from JNDI. You convert it to a String like this:

byte[] passwordBytes = (byte[]) someJNDImethod();
String password = new String(passwordBytes, "UTF-8");
