Hi Santosh,
I can remember that I have given you the REGEXP_REPLACE query earlier which you have specified and told you to read some document about it to modify according to your need. It is not very wise thing to depend on others every time.
Re: Removing Junk Characters.
Anyway, REGEXP_REPLACE(str,'[^[a-z,A-Z,0-9,chr(0)-chr(127)[:space:]]]*','') can give you some pointer (not tested).

Removing Non-Ascii Characters from a String

Hi Everyone,
I would like to remove all NON-ASCII characters from a large string. For example, I am taking text from websites and would like to remove all the strange arabic and asian characters. How can I accomplish this?
Thank you in advance.

I would like to remove all NON-ASCII characters from a large string. I don't know if its a good method but try this:
str="\u6789gj";
output="";
for(char c:str.toCharArray()){
if((c&(char)0xff00)==0){
output=output+c;
System.out.println(output);
all the strange arabic and asian characters.Don't call them so.... I am an Indian Muslim ;-) ....
Thanks!

How to remove non-ASCII charcters from an XML generated using Simple Transf

Hi,
I am currently facing a problem where I invoke a ST like
CALL TRANSFORMATION ZTEST
source root = str
result xml rawstr.
to prepare an XML using the contents of the ABAP variable str.
In my case sometime the variable str can contain non-ASCII characters. What I find is that ST do not remove these characters and the final XML that get generated thus contains non-parsable xml charcaters.
Is there an efficient way to remove/replace such non-ascii characters within the ST such that my final XML is consumable by any xml parser. I do not want to do a second level of processing by running through the output xml and removing the charcaters individually, because in our system the number of xml messages generated is very high and any such lookup-replace algorithm terms out to be too coslty.

Removing non-numeric characters from string

Hi there,
I need to have the ability to remove non-numeric characters from a string and I do not know how to do this.
Does any one know a way?
Example:
Present String: (02)-2345-4607
Required String: 0223454607
Thanks in advance

Dear NickM
Try this this will work...........
create or replace function char2num(mstring in varchar2) return integer
is
-- Function to remove Special characters and alphebets from phone no. string field
-- Author - Valid Bharde.(India-Mumbai)
-- Date :- 20 Sept 2006.
-- This Function will return numeric representation.
-- The Folowing program is gifted to NickM with respect to his post on oracle site regarding Removing non-numeric characters from string on the said date
mstatus number :=0;
mnum number:=0;
mrefstring varchar2(50);
begin
mnum := length(mstring);
for x in 1..mnum loop
if (ASCII(substr(upper(mstring),x,1)) >= 48 and ASCII(substr(upper(mstring),x,1)) <= 57) then
mrefstring := mrefstring || substr(mstring,x,1);
end if;
end loop;
return mrefstring;
end;
copy the above program and use it at function for example
SQL> select char2num('(022)-453452781') from dual;
CHAR2NUM('(022)-453452781')
22453452781

Non ascii characters being sent from a parameter in a form

Hi!
I have seen many topics posted on passing non ascii characters through parameters from one servlet to another and converting them into whatever format is necessary.
However, I have not seen anyone answer the following question. I have a jsp page (html) with the character encoding set to utf-8. The user inputs some data in to a text field which is inside a form. The data could be in non ascii characters such as hebrew or arabic. This form is then sent to another jsp where i try to retreive the data from teh text field. No matter what i do, i cannot get the data presented correctly. It is either question marks or other wierd symbols.
I have tried every permetation of encoding of the actual html page, the ecoding of the string from request.getParameter etc but it still is not presented on the new html page correctly.
Can anyone help??
Spencer

Ok, I solved the problem.
I had to put at the top request.setCharacterEncoding("utf-8");

Replacing non-ASCII characters with HTML charcter references

Hi All,
In Oracle 10g or greater is there a built-in function that will convert a string with non-ASCII characters like this
a b č 뮼
into an ASCII string with HTML character references like this?
a b & # x 0 1 0 D ; & # x B B B C ;
(note I had to include spaces between each character in the sample code for message to prevent the forum software from converting my text)
I tried using
utl_i18n.escape_reference( val, 'us7ascii' )
but for some reason it returns
a b c & # x B B B C ;
Note how it converted the Western European character "č" to its unaccented counterpart "c", not "& # x 0 1 0 D ;" (is this a bug?).
I also tried a custom solution using regexp_replace and asciistr (which I can't include here because the forum software chokes on it) but it only returns the correct result for values <=4000 characters long. Unfortunately asciistr doesn't appear to accept CLOB values larger than 4000 characters. It returns an error message like
(ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 30251, maximum: 4000) ).
I'm looking for a solution that works on CLOB data of any size.
Thanks in advance for any insight you can provide.

So with that (UTF8) in mind, let's take another look.....
As shown below, I used a AL32UTF8 database.
Note: I did not use a unicode capable tool for querying. So I set console mode code page to 1250 just to have č displayed properly (instead of posing as an è).
Also, as a result of using windows-1250 for client character set, in the val column and in the second select's ncr column (iso8859-1), è (00e8) has been replaced with e through character set conversion going from server back to client.
Running the same code on a database with a db character set such as we8mswin1252, that doesn't define the č (latin small c with caron) character, would yield results with a c in the ncr column.

Cannot login with password containing non-ascii characters

Hello,
I have web application, form based login. UTF-8 is specified "everywhere".
And it works, except for passwords.
If user register itself with password containing non-ascii characters, it is correctly written in database, but when doing either programmatic login or normal form based login, if fails.
If the password is only ascii, it works.
Username of login could be ascii or non-ascii, it doesn't matter, both works.
I'm using sun java application server 9.1.
jdbc realm.
I'm not using hashing passwords, just clean (now)
I tried configure realm Charset: UTF8 as last chance, but it doesn't work either.
The problem is only with non-ascii characters in password.
Any help very appreciated
Thanks a lot

hi,
I know all that, but that's not the case. My app uses preparedStatements, everything is properly configured, in all pages, utf-8 is going from user to db and back without any problems.
The only problem is with password field. As I am using form based login, with jdbc realm configured (again, nicely working when only ascii characters), I have very little chance to do something bad through the login phase.
I'm not talking about special characters, I'm talking about non-ascii characters, let's say - Chinese, arabish, Russian alphabet etc.
When user registers (my code), the fields are properly written to db. I have checked that, trust me.
But the Sun app server realm seems to have some problems with the password field.
(realm uses jdbc connection to mysql, the url contains all extra parameters to be sure about utf8. there is nothing more what can be configured...)
If I try other alphabet codes in login and ascii in password, it works. But soon, as I use other alphabet code also in password, it doesn't work anymore.
My only idea is, that I could try MD5 to create ascii only characters (I hope it works that way) on the client with javascript and then set Digest to MD5 in realm configuration. But still, it seems very strange. The clear way storage should also function? (now set Digest to 'none')
Is it a bug of Sun App Server?
thanks

Cannot rename file with non-ASCII characters when using the

My application moves files from one directory to another by calling File[] srcFiles = srcDir.listFiles() to get a list of files in the source directory, and then calling srcFiles.renameTo(destFile) to rename each file.
This does not work (renameTo returns false and the file is not moved) under the following circumstances:
- the file's leaf name contains non-ASCII characters, for example "�"
- the OS is Solaris 9
- the LANG and LC_* environment variables are unset, i.e. the C locale is being used
If I set the LANG environment variable to, for example, en_GB.UTF-8 then the rename succeeds.
I have tried calling srcFiles[index].getName().getBytes("UTF-8") and the non-ASCII characters are being replaced with ? (0x3f) characters when LANG is unset.
Is this a bug in the JRE? I would argue that since my code does not actually manipulate the filename (I just use the File object that File.listFiles() gives me) then the rename should succeed. Of course I would not expect the file name to be displayed correctly if I printed it out.
I have reproduced this behaviour with JDK 1.4.2_05 and 1.5.0_04 on Solaris 9.
Francis

Thanks for the info Alan.
I considered setting the locale in the environment (this sounds like the "correct" fix to me and we might implement it later), but this application shares a WebLogic server with many other applications so we would have to do a huge amount of testing to make sure that the locale change wouldn't break the other apps. In the end I worked around the problem by making the code that generates the filenames in the first place strip out any non-ASCII characters (the names of the files are not critically important).
Looking forward to JSR-203, in the meantime perhaps a note about this behaviour in the java.io.File javadoc would be useful.

Problems with non-ASCII characters on Linux Unit Test Import

I found a problem with non-ASCII characters in the Unit Test Import for Linux. This problem does not appear in the Unit Test Import for Windows.
I have attached a Unit Test export called PROC1.XML It tests a procedure that is included in another attachment called PROC1.txt. The unit test includes 2 implementations. Both implementations pass non-ASCII characters to the procedure and return them unchanged.
In Linux, the unit test import will change the non-ASCII characters in the XML file to xFFFD. If I copy/paste the the non-ASCII characters into the Unit Test after the import, they will be stored and executed correctly.

Problem with non-ASCII characters on TTY

Although I'm not a native speaker, I want my system language to be English (US), since that's what I'm used to. However I have a lot of files which have German language in their file names.
My /etc/locale.conf has en_US.UTF-8 and de_DE.UTF-8 enabled. My /etc/locale.conf contains only the line
LANG=en_US.UTF-8
The German file names show up fine within Dolphin and Konsole (ls -a). But they look weird on either of the TTYs (the "console" you get to by pressing e.g. ctrl+alt+F1). They have other characters like '>>' or the paragraph symbol where non-ASCII characters should be. Is it possible to fix this?

I don't think the console font is the problem. I use Lat2-Terminus16 because I read the Beginner's Guide on the wiki while installing the system.
My /etc/vconsole.conf:
KEYMAP=de
FONT=Lat2-Terminus16
showconsolefont even shows me the characters missing in the file names; e.g.: Ö, Ä, Ü

Non-ASCII Characters in AppleWorks

New to the forums and hope I'm not duplicating a prior post ... eons back, I used ClarisWorks on an old Mac SE/30, then moved over to AppleWorks which I got to use on my PC because I wanted to go back and work on something I had from years ago. The document in question contained non-ASCII characters. Anyway, I imported it into AppleWorks and what was once a Cyrillic font, was converted to ASCII (now a bunch of gibberish). I fully recognize I need to find the original font I used for the Cyrillic, but before I go that route, it looks like AppleWorks doesn't support non-ASCII characters ... ergo, I'm wasting my time. Am I wrong?
Thanks.

Validation for non-ASCII characters

Hi all,
Requirement: I have to apply a validation on on fields like Name and Address in applicationdefination.xml. When a user types non-ASCII characters and navigates to next page then it should display the error message. Thus, I have to restrict my user to ASCII values only.
Present Situation: I'm using regular expression for this problem. In Jheadstart there is an option regular expression under the heading Validation. I have written following values in regular expression and Regular Expression Error Message options.
Regular Expression
^\s*[\w\.\,\-\_\#\'\/\\\ u0022\u0026\*\;\:\s]+\s*$
Regular Expression Error Message
It is important to note that foreign characters are not accepted on our system. Please ensure only standard English letters are entered
Since, i was getting error in jspx page due to double quotes(") and ampercent(&), So i have replaced the double quotes(") and amprecent(&) by their unicodes. Thus, the expression has become like ^\s*[\w\.\,\-\_\#\'\/\\\u0022\u0026\*\;\:\s]+\s*$.
This expression is validating many characters like Ã,µ,Ç,Ï,Ö,§,¥,{,} but not all non ASCII characters like ѓ є ѕ ї Њ Щ Ώ Ω Ϊ Ά Ή Θ Λ Ξ Π τ ẫ ờ Ỡ Ứ Ỷ ự Ẁ ỹ ị Ọ ň ũ ť ţ Έ Ϊ ﻍ. Thus, its not fulfilling the requirement.
Please suggest some valid solution to this problem. It’s very urgent.

Hi,
The validation seems to be performed in Java or Javascript depending on the layout (I'm sorry I can't remember the exact details). The expression suggested above by theEternalStudent works very well in Java, but not in Javascript.
We came up with an expression which works in both. It rejects strings which contain &# by doing a lookahead before the main pattern - you might want to expand this to look for &#nnn; but for our purposes &# is enough.
Here is the "platform neutral" solution:
(?!.*\u0026#.*)^[\w\.\,\-\_\#\'\/\\\u0022\u0026\*\;\:\s]+$
I think in future we will write a javascript function and amend the templates to call it directly.
thanks,
Michael
