Converting ANSI characters to UTF-8 in Java

Is there any way to convert ANSI strings to UTF using Java

I have one using readutf & amp; Custom serializer for The writeutf method of the datainputstream class is used to deserialize and serialize strings If I receive an ANSI encoded string that is too long, about 100000 characters, I get an error;

However, in my JUnit test, I was able to create a 120000'a string, which was perfect

I have checked the following posts, but there are still errors;

Solution

This error is not caused by character encoding This means that the length of UTF data is wrong

Editor: just realized that this is a write error, not a read error

UTF is only 2 bytes long, so it can only hold 64K UTF - 8 bytes You're trying to write 100k, it won't work

This limitation is hard coded and cannot solve this problem,

if (utflen > 65535)
    throw new UTFDataFormatException(
            "encoded string too long: " + utflen + " bytes");
