Double byte chars in URI

Is it possible to send double byte chars through a URI? Is this possible to send from a servlet to a client browser then the client browser will just forward it on back to a server. What would have to happen on the server and client side for this to happen?
I guess I have basic non-understanding on how encoding works through http, using a client browser and also sending a response to a servlet container. Can anyone tell me how this process works? What are the default encodings, what is configurable on the client side or server side, etc.? Thanks.

I believe the rule is that you first have to encode the string into UTF-8 bytes, then apply the URL-encoding rules to that array of bytes. At least, that's how I understand the most recent rules for HTTP. But it's likely that most browsers don't follow this rule properly, so be prepared for a rough ride if you try this.

Support for Double Byte Chars in Table Names

Can you please tell me if double byte characters are supported in table names? Thanks.

Assuming you are using the same double byte character set as your db character set, then the answer is yes. Check out this table in the 9i Database Globalization Support Guide, for more info.
http://technet.oracle.com/docs/products/oracle9i/doc_library/release2/server.920/a96529/ch2.htm#103678

Function module to control printing of double byte chinese characters

Hi,
My sapscript printing of GR Slip often overflow to the next line whenever a line item encountered article desciption text in CHINESE.
The system login as "EN" but we do maintain article description in ENGLISH, ChINESE and mixture of both.
This result in different field length when printing.
Is there a way to control it and ensure that it will not overflow to the next line?
How does SAP standard deals with this sort of printing, single & double byte chars?
Please assist.

This is the code that solved our issue.
Besides we set the InfoObject to have NO master data attributes: it was just used as text attribute in an DSO, not as dimensional attribute in a cube. This solved the issue of the SID value generation error.

Double byte language i.e Japanese or Chinese text in non Unicode System

Hi,
I have translated text into Chinese and Japanese in a Unicode system and want to move it into a non Unicode system. Would Chinese/Japanese characters display correctly in a non Unicode system when moved from Unicode system. I am doing translation in ECC60 or SAP 4.7 Unicode system and moving to SAP 4.7 non Unicode system.
Thanks
Balakrishna

Hi Balakrishna,
in general the transport between Unicode and Non-Unicode systems is supported.
However there are restrictions, which are outlined in SAP note 638357.
In your case it is a prerequisite that the objects to be transported are language dependent (text lang. flag is set on the language key - see SAP note 480671) and the languages are properly setup in the target systems.
For double byte data there is a specific issue when transferring data from Unicode to Non-Unicode:
In a Non-Unicode system, one double-byte character needs two bytes, therefore e.g. in a 10 char field, 5 double byte chars are fitting. In a Unicode system, you can insert 10 double-byte chars in a 10 char field. Hence there is a risk of truncating characters in case of Unicode --> Non-Unicode communication.
Please also have a look at SAP notes 1322715 and 745030.
Best regards,
Nils

Invoke-WebRequest - Double byte characters issue in windows 8.1

I try write a powershell script to download a file from web server but failed. The path have double byte characters.
I could run in Windows server 2012 and 2012 R2 successfully, but fail in Windows 8 & 8.1
Do there any difference below Windows server and client powershell?
Region and setting are same in Windows 2012 & Windows 8
Script as below
Invoke-WebRequest -Uri " http://hostname/m/%E9%...../......./...../xxx.jpg"

Security settings are one possible cause of this.
Since we don't have your URL we cannot reproduce this.
It is "different". Using "difference" had me confused for qa bit. I though you were trying to figure out the difference between two things.
Use:
$wc=New-Object System.Net.WebClient
$ws.DownloadFile($url,'c:\file.jpg')
You will see less issues and it is faster.
¯\_(ツ)_/¯

JSF and Double Byte Character

Hi,
I wanted to know how to handle <h:outputText> with chinese character or double byte character.
See sample code below :
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<h:form styleClass="form" id="form1">
<% request.setCharacterEncoding("UTF-8"); %>
<h:inputText styleClass="inputText" id="text1"></h:inputText>
<hx:commandExButton type="submit" value="Submit" styleClass="commandExButton" id="button1" action="#{pc_SubmitTest.doButton1Action}"></hx:commandExButton>
<h:outputText styleClass="outputText" id="text2"></h:outputText>
</h:form>
When you input with double byte character and submit,
the output screen value did not render properly .
I tried this similiar code at JSP, it work fine.
Anybody know how to solve this problem ?
Anything need to do at pagecode level ?
Thank you.

Problem was due to the fact that I was trying to generate the excel file in char stream instead of byte stream

ASCII representations of double-byte characters

My file contains ASCII representations of double-byte CJK characters (output of native2ascii). How do I restore them back to the original native characters?
I mean, when I load the file with FileInputStream, what I get are all strings like \uabcd. How do I get the characters represented by these strings?

My file contains ASCII representations of double-byte
CJK characters (output of native2ascii. How do

I am no expert in unicode so I don't know if this is correct, but I assume that if a String starts with "\u" then there will be 4 more characters that are a hexadecimal representation of the char value. If that's right, then you should be able to parse out the "\uxxxx" and convert it to a char by parsing the hex. For example//the variable unicode is a String like \uabcd
String hex = unicode.substring(2);
char result = (char) (Integer.parseInt(hex,16));

To find out whether a character is of Single byte or Double bytes

hi,
is there any built-in class to find whether a character is a single byte or double byte. is there any method to do so?? If possible can someone provide a sample code snippet to do a check for single byte and double byte characters.
thanx in advance.....

If you are asking what size the char primitive is, it's 16 bits.
If you want to know the numerical value of a char, you can cast it to an int and compare it to 255 to see if it fits in 1 byte.

Right Truncation, varchar in SQL Server, double-byte in Oracle

Hi.
We have a DB Link using DG4MSQL from Oracle 11.1.0.7.0 to a SQL Server 2005 database. The Oracle database is set up to use UTF-8 so all character fields are double-byte on the oracle side.
On the SQL Server table we have a column defined as varchar(32). When doing a select * from this table (from Oracle, over the DB link), everything works fine if that column contains values with a length of 16 characters or less. When the column contains 17 - 32 characters we get the following error:
Error report:
SQL Error: ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC SQL Server Driver]String data, right truncation {01004}
ORA-02063: preceding 2 lines from SQLUAT
28500. 00000 - "connection from ORACLE to a non-Oracle system returned this message:"
*Cause: The cause is explained in the forwarded message.
*Action: See the non-Oracle system's documentation of the forwarded
message.
It looks like Oracle (or the ODBC driver) is bringing the data back as double-byte even though it is declared as varchar. If we change the column on the SQL server side to nvarchar, everything works fine.
Is this a bug? Or is there a setting that can be specified for the gateway so that it recognizes SQL Server varchar columns as single-byte, to prevent them from coming over as double-byte and messing up the ODBC driver? Or is there anything else we should do to prevent this problem?
Thanks

Hi,
I don't think it's a problem with the hs or the dblink (but I may be wrong):
UTF-8 is double-bytes as you said. when you declare varchar2(32) it actually means you can insert up to 32 bytes --> 16 characters.
even if you do a simple insert to the table with more than 16 characters - it will fail.
In order to overcome this you should declare the table with varchar2(32 char) which will tell Oracle to allocate enough bytes to hold 32 chars - not bytes. In UTF-8 this means 64 bytes (2*n). If you'd be using AL32UTF-8 this would mean 4*n.
BTW- why are you using UTF-8 and not AL32UTF8?
Hope this helps.
