How to find an extended ASCII character

Hi,
I have a problem while reading from a InputStream with a BufferedReader. I�m trying to find out if an extended ASCII character is within a String made with readline(), but it always says no. Example:
myString.indexOf('\u00D2')
While debugging, I see that the character is a '?'.
How can I find this extended ASCII character ('\u00D2') ? Is it an encoding matter?
Please help!!

You are using a default character encoding when you use BufferedReader, so the text you read is probably translated to some other character in some cases (two or more bytes can sometime make up a new unicode character depending on the encoding).
You could try this:
BufferedReader br = new BufferedReader(new InputStreamReader(in, "IS0-8859-1"));where in is your InputStream.

YadalaThis should match your requirement:
select t.TABLE_NAME, t.COLUMN_NAME from ALL_TAB_COLUMNS t
where length(asciistr(t.TABLE_NAME))!=length(t.TABLE_NAME)
or length(asciistr(t.COLUMN_NAME))!=length(t.COLUMN_NAME);The ASCIISTR function returns an ASCII version of the string in the database character set.
Non-ASCII characters are converted to the form \xxxx, where xxxx represents a UTF-16 code unit.
The CHR function is the opposite of the ASCII function. It returns the character based on the NUMBER code.
ASCII code 174

How to find out the ASCII Values for Spanish character

Hi,
I had an requirement to store Spanish character and also need to fileter the records based on the Spanish character.
Kindly guide me for below.
To filter the Records which contains spanish characters?
To get the ASCII Values for the particular column?
E.g. we can find out the ASCII value of 'a' by using the syntax select ASCII('a') from dual.
But I want to find the ASCII Values for the particular column value. Ie. name.
E.g., Client name is "Suresh", I want to the ASCII Values for entire name of "Suresh".
Kindly do the needful help / Guidance on this.
Thanks,
Orahar

To expand on what I said in my first post, you want to do something along these lines:
with t (thename) as
select 'Suresh' from dual
select thename
     , substr(TheName, level, 1)
     , ascii(substr(thename, level))
from t
connect by level <= length(thename);The output of the above query is:
THENAM S ASCII(SUBSTR(THENAME,LEVEL))
Suresh S                           83
Suresh u                          117
Suresh r                          114
Suresh e                          101
Suresh s                          115
Suresh h                          104
6 rows selected.Note that the WITH statement is only there to simulate a table for this example. With a table, all you do is get rid of the with and substitute the name "t" for the name of your table (also the name of the column to whatever name the column has in your table).
Lastly, I suggest you post your question along with, an example table and the output you'd like to get in the PL/SQL forum. There are people there that will give you all kinds of great ways of solving that problem.

How do I convert an ASCII character to an array of co-ordinates.

I need to convert and ASCII character to an array of X, Y co-ordinates. I also need to be-able to vary the size of the text (scale of graph i suppose) and position on the graph So i can desplay multiple characters on a graph. However it needs to be stored in an array (or set of arrays) so i can isue these co-ordinates to an instrument.

Maybe the attached VI can help. Using picture control functions, it get the
1bit bitmap of the character/text
on input in a 2D array of booleans.

Extended ascii character problem

Here is the message I am getting
2004-10-12 10:04:44,207 ERROR [STDERR] org.postgresql.util.PSQLException: Invalid character data was found. This is most likely caused by stored data containing characters that are invalid for the character set the database was created in. The most common example of this is storing 8bit data in a SQL_ASCII database.
this is the character that is causing the problem (ascii 0232 �)
My question is how can I make java display this character. I am using Postgresql 7.4 as my database.

I don't understand the connection between the database and "java display".
And ASCII is a 7 bit character set, so the character you listed is not ASCII, rather it is a character in some other character set.

Extended ASCII character problems

We are having problems with certain characters. If a character in the range ASCII 194-239 appears in a string it can cause the next character to be lost. Everything seems okay in SQL, but not in PL/SQL.
A PL/SQL script to print all the ASCII characters outputs nothing for the above range.
e.g.
DECLARE
v VARCHAR2(100):= 'Requiem por un PolicÃ|xxx|qqq';
BEGIN
dbms_output.put_line(instr(v,'|'));
dbms_output.put_line(substr(v,instr(v,'|')));
END;
The expected results would be 22 and |xxx|qqq, but we actually get 25 and |qqq. The first '|' is being lost somehow.
A test using a Java function retrieving the string from a table failed due to a conversion failure between UTF8 and UCS2.
The NLS language is AMERICAN and the character set is UTF8.
Thanks
Steve

I know this thread is old, but it took me forever to find this out...
Use:
SELECT CHR (<ASCII Value> USING NCHAR_CS) FROM DUAL;
E.g.
SELECT CHR (206 USING NCHAR_CS) FROM DUAL;
CHR (206 USING NCHAR_CS)

How can i convert an ascii character to a number?

where can I find the function?

A string will be converted to an array of U8.
Unless you convert a single character.

How to find length of a character variable in sap script

Hi,
I have stored a line of text in one variable. If the text exceeds more than 50 characters, the remaining characters will be printed in next line.
For this i have given code as :
<I>&S_BOL_SUMMARY-TXT(50)&</>
<I>&S_BOL_SUMMARY-TXT+50&</>
The problem is i have to print the second line only when the text exceeds more than 50 characters. So how can i give the condition for that?
Ezhil

Hi,
Try the following,
data: len type i.
len = strlen (S_BOL_SUMMARY-TXT ).
if len > 50.
&S_BOL_SUMMARY-TXT(50)&
&S_BOL_SUMMARY-TXT+50&
else.
&S_BOL_SUMMARY-TXT(50)&
endif.

Is Java or C++ retrieving data from postgreSQL?

Is the data UNICODE at all times? [Probably not]
What other encoding is used?
Do you have logging of bytes and chars where relevant?

How to query for extended ASCII characters in column value

How to write extended ASCII characters to a file

Here is a distilled fragment from some larger script. Its purpose is to create a text file containing some characters from the extended ASCII character set.
$String = "Test" + [char]190 + [char]191 + [char]192
echo $String | out-file d:\test.txt -Encoding ascii
What I want in the target file is exactly the 7 characters that make up $String. The above method fails to deliver this result. How can I do it?

Hi,
Try using Add-Content or Set-Content instead:
$String = "Test" + [char]190 + [char]191 + [char]192
echo $String | Set-Content .\test.txt

SQL Developer, UTF8 Oracle DB, extended ascii characters appear as blocks

I have this value stored on the database:

Notice the second word has an extended ascii character in it. When I use SQL Developer on my windows machine to view the data, I get a box in place of the o, kinda like this:

If I log on to the AIX server where the oracle database in question is and run sqlplus from there, I see things properly. I also managed to regedit oracle home to get sql plus on my windows machine to display this properly. I still cannot get sql developer to work though...

This problem is quite strange in that when I've been able to manually set American_america.utf8, things work.Sorry to say, but it seems you may have an incorrect setup.
In general, you should set char set part of NLS_LANG to let Oracle know the code page used by the client. With win-1252, NLS_LANG should include .WE8MSWIN1252.
The display from sqlplus was "lying", due to incorrectly stored data coupled by incorrect nls_lang setting (char set part). The pass-through or gigo scenario can be dangerous this way. Search the Globalization forum for the term 'pass-through' for previous discussions on the theme.
The setting on AIX servers may be incorrect as well, but it depends how you use it (e.g. for database export or data load with utf-8 encoded files it may be correct).
The output of the query you recommended looks odd to me:
(Gestion Econ�mica o Facturaci     Typ=1 Len=30 CharacterSet=UTF8:
28,47,65,73,74,69,6f,6e,20,45,63,6f,6e,f3,6d,69,63,61,20,6f,20,46,61,63,74,75,72,61,63,69;This is the telling part. The 0xF3 is not legal in UTF8. Actually, the code units for ó, U+00F3 Latin small letter o with acute, are C3 B3. So instead of f3 you should have expected c3,b3 from the dump output.
>
So it looks like what's under the covers is correct, but I'm still not seeing the correct character in sql developer.The opposite is true. Data is incorrectly stored and SQL Developer is correctly showing you this. Sqlplus is not the best tool in Unicode environments, SQL Developer is better.
>
ACP according to my windows registry is 1252. OEMCP is 437Also, if you use database clients in console mode (such as sqlplus), NLS_LANG should include .US8PC437 to properly indicate that code page in use is 437.
