I have a problem with encoded string. I have a string that returns from soap request in my android app.public static String decrypt(String key, String ivs, String encrypted) try IvParameterSpec iv new IvParameterSpec(ivs. getBytes("ISO-8859-1")) SecretKeySpec skeySpec new I have a problem with encoded string.byte[] encrypted cipher.doFinal(value.getBytes("ISO-8859-1")) String r Base64.encodeToString(encrypted, Base64.DEFAULT) new InputStreamReader(is, "ISO-8859-1")) String s r.readLine() System.out.println("test. java:9 [byte] (char)" (char)s.getBytes()[0] ".To represent arbitrary binary data in text and convert it back to binary data later, you should use base16 or base64 encoding. java.nio.charset.Charset has been introduced in JDK 1.4.

Charset plays the role of encoding and decoding between given charset and UNICODE.ISO-8859-1: ISO Latin alphabet UTF-8: This is 8 bit UCS transformation format.ByteBuffer.wrap(s.getBytes()) CharBuffer cb charset.decode(bb) Does anyone know how to convert a string from ISO-8859-1 to UTF-8 and back in Java?Conversion between UTF-8 and ISO 8859-1: getBytes(Charset charset) results in a byte array encoded using the charset, so latin1 is UTF-8 encoded. I am trying to convert a string encoded in java in UTF-8 to ISO-8859-1.When I do a getbytes(encoding) and then create a new string with the bytes in ISO-8859-1 encoding, I get a two different chars. String objects in Java use the UTF-16 encoding that cant be modified. Technically speaking, byte[] doesnt have any encoding.String value new String(myString.getBytes("UTF-8")) and, if you want to read from text file with " ISO-8859-1" encoded: Note. 0.

The method getBytes() in java.lang.String converts implictly with native encoding. The usage of this method on machines where native encoding is not ISO- 8859-1 or some compatible ASCII encoding is wrong in J2SE SDK 1.4.2 in the following cases. Other notes : - my JVM starts with ISO1 encoding parameters and I cannot change it.String convertedStr new String(originalStr.getBytes("ISO8859-1"), "ISO 8859-2") Vladimir. Subject: Re: java : convert a string to UTF-8 From: brunob-ga on 13 Jan 2005 09:37 PST. OldStr.getBytes (String encoding) is String Unicode encoding Java inside the encoding byte in the specified format.ResultSet rs String rs.getString (STR) STR new String (str.getBytes (" iso8859-1"), "GB2312") This encoding conversion efficiency. Why isnt the above code equivalent to data.getBytes("ISO88591") instead?However, in your comment to the earlier answer, you guarantee that there are no character values greater than 0xFF in the string, then youre doing something wrong. byte[] latin1 sb.toString().getBytes("ISO-8859-1") return new String(latin1) Im not quite sure whats going awry, but I believe its readLine() thats causing the grief (since the strings would be Java/UTF-16 encoded?). The Java String getBytes method is used to encode the given string into sequence of bytes using the user specified charset, and return Byte array.System.out.println("nDecryted Text " s2) byte[] bArray str. getBytes("ISO-8859-1") The getBytes() method encodes a given String into a sequence of bytes and returns an array of bytes.Example: getBytes() method. import java.io. public class GetBytesExampleISO-8859-1: ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1. UTF-8: Eight-bit UCS Transformation Format. Since char is 2 bytes in Java, so String.getBytes().length will be 2x of String.length() if the encoding is UTF-16.So it has to be something on the RH9 that makes it not working. The only difference I can see now is the encoding, utf-8 vs iso-8859-1. I am trying to convert a string encoded in java in UTF-8 to ISO-8859-1.When I do a getbytes(encoding) and then create a new string with the bytes in ISO-8859-1 encoding, I get a two different chars. The getBytes() method of Java String class, generally, converts or encodes a String into a byte array.Lets see this method in more detail. The Java getBytes() from the String class has the following three formsSystem.out.

println("Value: " Str2) Str2 Str1.getBytes("ISO-8859-1 " Which original encoding should be ISO-8859-1 and when I convert it to UTF-8 it should generate.In Simple Words ,if you want to convert charsetiso-8859-1 to java string (which is UTF-8 by default). String response new String(input.getBytes("ISO-8859-1"),"UTF-8") GetBytes("ISO-8859-1") return new String(latin1) In Java, String/Char is always in UTF-16BE. Different encoding is only involved when you convert the characters to bytes. The classes java.io.InputStreamReader, java.io.OutputStreamWriter, java .lang.String, and classes in the java.nio.charset package can convert between Unicode and a number of other character encodings.ISO-8859-1. convert from internal Java String format -> UTF-8 public static String convertToUTF8( String s) String out null try out new String(s.getBytes("UTF-8"), "ISO -8859-1") catchISO-8859-1 encoding is just used to transfer 8 bit array into a String. Given the String "645553dd" in Java, I can extract a series of bytes using . getBytes("ISO88591") that looksYou should be able to convert from the Buffers default encoding of UTF-8 to ISO-8859-1 with iconv: var Iconv require(iconv).Iconv var ic8859 new Iconv(UTF-8, ISO-8859-1) Code example from Github project UnicornButter/libcore, OldAndroidInputStreamReaderTest. java ».if (encoding.equalsIgnoreCase("UTF-8")) . Charset charset Charset.forName(" ISO-8859-1"buf ByteBuffer.wrap(cs.getBytes()) ByteBuffer buf charset.encode(cs) String cs2 new String If you call s.getBytes("ISO-8859-1") everywhere instead of s.getBytes() I suspect youll get back the right byte value but relying on ISO-8859-1 for this is kinda dirty IMO.JAVA String Encoding Conversion Issues. new String(stmt.getBytes("iso-8859-1"), "UTF-8").The reason why ISO-8859-1 usually works is that this encoding doesnt modify any char with a code point < 256 (i.e. anything between 0 and 255), so UTF-8 encoded byte sequences wont be modified. Java tries to use the default character encoding to return bytes using String.getBytes().So, why is there an intentional fallback to ISO-8859-1 in the getBytes() method? getBytes(String charsetName): Encodes this String into a sequence of bytes using the named charset, storing the result into a new byte array.Str2 Str1.getBytes( "ISO-8859-1" ) System.out.println("Returned Value " Str2 ) Java tries to use the default character encoding to return bytes using String.getBytes().So, why is there an intentional fallback to ISO-8859-1 in the getBytes() method? byte[] isoBytes line.getBytes("ISO-8859-1") System.out.println(new String(isoBytes, "UTF-8")) See also questions close to this topic. Javas var inference only in local variables. The java.io.InputStreamReader, java.io.OutputStreamWriter, java.lang. String classes, and classes in the java.nio.charset package can convert between Unicode and a number of other character encodings.ISO-8859-1. Many methods exist in java.lang.String class used for different string manipulations like checking the availability of agetBytes() returns a byte array where elements are ASCII (depends on charset encoding) values of theCharsets UTF-8 and ISO-8859-1 are default for many operating systems. getBytes(String charset) method throws a checked exception UnsupportedEncodingException.tFactory.newTransformer() byte xmlbytes[] xmlStrBuf.toString(). getBytes("ISO-8859-1") StreamSource streamSource new StreamSource( newIt certainly wont do anything useful. As I said all Java strings are in Unicode. If you want to convert something from one encoding to another Unicode and Java data types. Before tackling the encoding API, it is a good idea to get a handle on how text is represented in Java strings.byte[] thisAppCanBreak "this app can break" .getBytes("ISO-8859-1") CharsetDetector detector new CharsetDetector() detector.setText Java String getBytes() Method - Learn Java in simple and easy steps starting from basic toDescription. This method encodes this String into a sequence of bytes using the platforms default charset, storing the result into a new byte array.Str2 new String (Str1.getBytes( "ISO-8859-1" )) Especially for the ISO88591 encoding, Java 8 introduced logic that simply casts each char in the array to a byte, giving a huge performance increase.Java 7 String.getBytes(): 200-300 ns/op Java 8 String.getBytes(): 70-80 ns/op Custom logic: 90 ns/op (on both Java 7 and 8).

Welcome to the CSDN-markdown editor1 years ago885 Views. At the same time, String.getBytes(UTF-8) does not work that quickly for non-ASCII encodings besides more complicated mapping, it has to allocateThe difference between Java 7 and 8 versions of ISO88591.java is that Java 7 contains all encoding logic in the single method, but Java 8 has a (You can just use the String constructors and getBytes methods, but personally I dont like just working with the names of character encodings.Every instance of the Java virtual machine has a default charset, which may or may not be one of the standard charsets. [US-ASCII, ISO-8859-1 a.k.a I am trying to convert a string encoded in Java to UTF-8 to ISO-8859-1. Say for example, in the string aabcd is represented in ISO-8859-1 by E2. In UTF-8, it is represented by two bytes. C3 A2 I believe. When I do a getbytes (encoding) and then cre. I am not able to print other language characters. What could be the problem? Sample code: [code java]import java.io.UnsupportedEncodingException impo.String encoding and decoding. Sajin Balakrishnan. Greenhorn. Java String getBytes(String charsetName).
