Unicode to hex conversion

Guys, I look at ASCII table given to me for Czech chars and hex value for character "á" is E1. But when I use rawtohex function to get hex value I get below output.
WHY ?
SQL> select rawtohex('á') from dual;
C3A1
How can I get value E1 ? Thanks

Character to hex conversion

Hi,
How can i convert character into hex string , for example if i have the data as "testing data", how can i get the hex coded output? Ive tried out using first string to number vi and thennumber to hex conversion vi but i get the answer as 0, can u help me in this?
In short my data is " testing1234okokok" , i want a hex coded output which would be something as "AD87BA......."
Please help

Interger to hex conversion ???

Hi
Is there a easy way to make interger (unsigned 32 bit ) to HEX
conversion ??

Kristian,
It depends on what you want to do with the hex conversion. To view a
number in hex in a control, right click on the control, select Format &
Precision. As long as the format is set to numeric, you can select
between decimal, hex, octal and binary from the other drop-down list.
If you want to change an unsigned 32-bit number to a hex value to be
written to a file, you can use the String->Format Into String VI. Wire
your U32 into input 1, and set the format string to %4x (which will show
a 4 digit hex value). The output will be a string which contains the
hex value.
Hope that helped.

Problem with EPC URI to Hex conversion

Hi Forum,
I am getting strange EPC URI to hex conversion result in tx:/ain/http_test . Could you please confirm if this result is not expected.
1.URI : urn:autoid:tag:sgtin-96:3.0066800.054321.70
hex is : 30740413C00000D431000000
2.URI: URN:AUTOID:TAG:SGTIN-96:3.0066800.054321.71
hex is: 30740413C00000D431000000
thus is both case HEX is same!!!
i am using EPC_1.24 as active EPC version.
could you please suggest some round about way.
thanks in advance,
regards,
Ashit

hi,
i think problem is with EPC_1.24. i changed to
EPC_1.27
and it works fine.

Convert Unicode to Hex (Big5 hex)

i have a content in MySql as Blob type. The content is a string of unicode. The below string is the content.
82f1570b5a929ad4900f9732002c67008fd16df153d75b9853f87e8f8eab76849ea553ef5091905c62537b9754119ed15e6b592780337abf501f9322002c4ee589e36c7a4ed69ad890544e0051044e8c5343842c7f8e91d1768450b552d9002c800c9ea553ef5df2548c5c0d65b9800159276210597d53cb002e
This is representing a sentence of chinese character. Well, for instance:
82f1 - ying
570b - guo
(ying guo = England country)
My question is, how can i convert 82f1 into Big5 format? Eg: "82f1" will becomes "AD5E".
Anyone has idea to convert it? Thanks

this might be helpful as well
String s = "abcdef";
byte[] bytes;
try {
bytes = s.getBytes("UTF-16BE");
catch (java.io.UnsupportedEncodingException ex) {
for (int i = 0; i < bytes.length; ++i) {
System.out.print
(Integer.toHexString(bytes|0x100).substring(1,3) +
First of all, thank you for replying. This above code showed conversion from char to hex. But my problem is to convert from UTF-16 to Big5. Every 4 digits (82f1) is representing a char in chinese encoding. Therefore, i am looking a way to convert every 4 digits back to Big5 encoding. Do you have any idea of that? :)

Hex conversion problem... Please help

Hi all,
I need to convert a hex character representing a UTF-16 character to a hex string representing a UTF-8 character
i.e
String input ="0x0630"; //ARABIC LETTER THAL (UTF-16)
I want the output to be a hex representation of the same charcter in UTF-8.
Does anyone know the java code to do this?

As BIJ001 already implied: There are no "UTF-8 characters" and "UTF-16 characters". There are Unicode characters and their respective UTF-8 and UTF-16 encodings.
For example:
"ذ" is the arabic Letter Thal. Its name in the Unicode standard is ARABIC LETTER THAL. Its is the Unicode codepoint (decimal) 1584. This is often written as U+0630 (note that this number is hexadecimal).
The UTF-16 encoding of this letter is the 16bit word 0x0630 (the UTF-16 encoding of most common characters is identical to its codepoint, but that's not always the case!).
The UTF-8 encoding of this letter are the two 8bit words 0xD8 0xB0.
If you have the String "0x0630", then you can split the hexadecimal number from the String, parse it, interpret it as a char, and create a String from it. Then call getBytes("UTF-8") on it and you'll have a byte array containing the UTF-8 encoding of that character.
[_The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)_|http://www.joelonsoftware.com/articles/Unicode.html] is a nice explanation as well.

From Unicode to IS08859_1 conversion

Hi everybody!
I'm trying simply to correctly display some special characters like �,�,�,�,�,�.
I can decode correctly any RFC2047 compliant string, but the output string is in Unicode(UTF8) format, since this is the Java's native charset.
Then I tried to convert the string to the ISO-8859-1 another charset in two ways:
1) string = new String(string.getBytes(),"ISO8859_1");
2) import sun.io.CharToByteConverter;
CharToByteConverter fromUnicode = CharToByteConverter.getConverter("ISO8859_1");
string = new String(fromUnicode.convertAll(string.toCharArray()));
Both of these gave me the same result.
Are they equivalent? (yes, I suppose).
Anyway, trying to convert to some charsets (like SJIS, Cp307) it works fine, but trying to convert to other charsets (ISO8859_1, Cp1202) it seems not to perform any conversion:
the result is the same I obtain deleting the code descripted above.
Can anyone give me help?
Thank you all.
Gi_gio.

1) string = new String(string.getBytes(),"ISO8859_1");This is likely to do nothing because here's what happens: It converts "string" to an array of bytes using the default encoding for your platform, which is most likely ISO8859-1. Then it converts that array of bytes back to a String, using ISO8859-1. So... no change.
Every time you think "I need a string in xxx format", slap yourself on the hand. A Java String is not in any format but Unicode. There is no such thing as a UTF-8 String or an ISO8859-1 String. If you need data in a particular encoding, you need an array of bytes in that encoding. In other words if you need your String in ISO8859-1 encoding, you do this:
bytes b[] = string.getBytes("ISO8859_1");

Unicode huge file conversion problem

I use the command in Unix "sapiconv -f 4110 -t 8600 -o <source file name> <destination file name>" calling by ABAP command "CALL 'SYSTEM' ID 'COMMAND' " to convert non-unicode source file to unicode destination file in code page 8600 (Thai language). For the small size source file, It has no problem, but for the huge size source file (27MB - the file was extracted and created by OPEN DATASET from asset master data about 95000 records), it has problem. There are only about 1300 Records (about 200k) in destination file and the remain records are missing!?!? And every time I run the program, It still has certain result.
What can I do for this case? or the command 'sapiconv' has the size limitation for unicode file conversion? or which additional parameter should I use?
Thank you in advance.

Unicode to String Conversion

Dear all,
I'm trying to get the String from unicode, previously i'm converting the String to Unicode like below,
String s = "\\u"+Integer.toHexString(s.charAt(0));
Which is giving me the same what i appended above even after Conversion using UTF-8.
If i do String s ="\u30f3"
It is giving me correct character. But my problem is i'm getting the latter part i.e hexString latter in the run time...through Integer.toHexString..
i can't add this as a character.. so it is taking as a two different strings..
How to handle this situation..
Hope i can find the answer,
Thanks in advance,

Numeric to hex conversion

Hi
i am new to labview. i have implemented a controller circuit and serially communicating with using lab view in that i am using a numeric value and converting it to hex using numeric to hex string and receiving that on port 1 of controller but that is displaying ASCII values of my number though i have converted it in hex in block diagram of labview.

Hi
I have problem in labview to my hardware communication. when i am using (testing) code for my controller and using CS100FULL.vi then i get whatever data i send on assigned ports. But i want total 12 bit data to deal with and thats to in hex form insted of ASCII so i do the necessary changes in controller code(testing1) and making change in vi also keeping width of decimal to hex string conversion block 3. but i wont get any data at port.
Please please suggest me whwrw i am making mistakes because in keil this code runs properly and i get at desired data at ports in simulator but when i am loding it in controller it won't work with labview but when i am using hyper terminal it communicate properly and i get data at port 0&1 that
means i am doing mistake in vi so please suggest me solution and mistakes i am making in my vi.
Thank you

Float to hex conversion

Application A has a data type NUMBER and B has a data type BLOB. The data types cannot be changed since we don't have the source codes for both applications.
The data stored in application A is a float of negative value (--1.7029176). I need to convert it to hex (BFD9F934) and store it in application B to be able to use it.
Is there a way to code this in PL/SQL?

I guess you are looking for these conversion functions
SQL> select rawtohex(-1.7029176) from dual;
RAWTOHEX(-1.70
3E641F48542966
--" or "
SQL> select dump (-1.7029176,16 ) from dual;
DUMP(-1.7029176,16)
Typ=2 Len=7: 3e,64,1f,48,54,29,66

46C EBCDIC to UNICODE upgrade and conversion

Can the UNICODE conversion processed be used directly on a 46C EBCDIC source system? Or is a conversion to 46C ASCII required before a UNICODE conversion?

Hello Will,
as Sally already explained, this is unfortunately not possible ;-((
SAP does not support Unicode with 4.6C ;-(
Therefore, only EBCDIC and ASCII are the options.
As of 4.7 Unicode & ASCII are available.
=> the project could look as follows:
- On 4.6 you need to go from EBCDIC to ASCII - 12 - 24h conversion time
- Upgrade to ERP 6.0 EHP4 ASCII - total Runtime about 40-65h - downtime of that: 10-24h
- Unicode Conversion Latin1 - 6-14h conversion time
=> You see, that the total runtime in one step is pretty long - e.g. for X-mas ...
Otherwise, it is typical, that the ASCII CPC is done in one step and later on Upgrade & Unicode in one further step.
For more details, we should talk together, but at least your project is pretty big ...

Unicode and ascii conversion help needed

I am trying to read passwords from a foxpro .dbf. The encrpytion of the password is crude, it takes the ascii value of each char entered and adds an integer value to it, then stores the complete password to the table. So to decode, just subtract same integer value from each chars retieved from .dbf. pretty simple.
The problem is that java chars and strings are unicode, so when my java applet retrieves these ascii values from the .dbf they are treated as unicode chars, if the ascii value is over 127 I have problems.
The question. how can i retrieve these ascii values as ascii values in java?
Should I use an InputStream like:
InputStream is=rs.getAsciiStream("password");
Is there a way to convert from unicode to extended ascii?
Some examples would be helpful, Thanks in advance.

        return cbuf.array();

        Charset cs = Charset.forName("ASCII");
        CharBuffer cbuf = CharBuffer.wrap(c);
