Char to unicode value?

Is there a way to determine the unicode value for a char variable? And, is there a way to form a char variable knowing the unicode value? I am looking for something equivalent to the asc and chr functions in BASIC.
Thanks ...

I was a bit hasty. Remember to always check your results first.
Why does Character.getNumericValue(char ch); not yield the desired results as the api describes?
getNumericValue
public static int getNumericValue(char ch)Returns the Unicode numeric value of the character as a nonnegative integer. If the character does not have a numeric value, then -1 is returned. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.
Parameters:
ch - the character to be converted.
Returns:
the numeric value of the character, as a nonnegative int value; -2 if the character has a numeric value that is not a nonnegative integer; -1 if the character has no numeric value.
Since:
JDK1.1

I've always dealt with primitives in the past, but am always looking for ways to let the api do the work for me.

How to find as ascii value for a string or char in unicode system?

Hello,
How to find an ascii value for a string or char in unicode system?
Thanks in Advance

hi ,
report demtest.
data : c.
field-symbols : <n> type x.
data : rn type i.
c = 'A'.
assign c to <n> casting.
move <n> to rn.
write rn.
This will convert 'A' to 65.

How to convert ascii value to character.
If I give input as 65 (ascill value) I want display 'A'.
Below logic is for convert from character to ascii value , now I want to know how to convert ascii value to character.

Unicode value of a non-ASCII character

Hi,
Suppose, the unicode value of the character ् is '\u094d'.
Is there any Java function which can get this unicode value of a non-ASCII character.
Like:
char c='्';
String s=convertToUnicode(c);
System.out.println("The unicode value is "+ s);
Output:
The unicode value is \u094d
Thanks in advance

I have tried with the parameter
c:\ javac -encoding utf8 filename.java
Still I am getting the same print i.e. \u3fIf it comes out as "\u3f" (instead of failing to compile or any other value), then your source code already contains the question mark. So you already saved it wrong and have to re-type it (at least the single character).

Then I studied one tutorial regarding this issue
http://vietunicode.sourceforge.net/howto/java/encoding.html
It says that we need to save the java file in UTF-8 format. I have explored most of the editors like netbean, eclipse, JCreator, etc... there is no option to save the java file in UTF-8 format.That's one way. But since that is so problematic (you'll have to remember/make sure to always save it that way and to compile it using the correct switch), the better solution by far is not to use any non-ASCII characters in your source code.
I already told you two possible ways to achieve that: unicode escapes or externalized strings.
Also read http://www.joelonsoftware.com/articles/Unicode.html (just because it's related, essential information and I just posted that link somewhere else).

Parsing strings with Unicode values 16 bits

How can I get the Unicode value for a character in a String when the value is greater than 16 bits?
I need to extract a supplemental plane Unicode value from a string. However, String.charCodeAt(index) truncates the Unicode value to 16 bits, returning what should be 0x02F91A as 0xF91A. I see discussions that show that earlier versions of Flex stores such char codes as the two code points of a surrogate pair, but in Flex 4, the string length is just 1 when I put only this character in the string.

Does it work in JavaScript? Could send it over via externalInterface.

Determining Unicode Values

Is there a reliable way to determine the Unicode value of any character? For example, the following codeString string = "Việt";
for (int i = 0; i < string.length(); ++i)
char c = string.charAt(i);
System.out.println(c + " = " + Character.getNumericValue(c));
}Gives this output:
V = 31
i = 18
? = -1
t = 29
Not too helpful, since the one character I really care about is shown as -1.

Well, I'm still somewhat confused (and, in my
corporate environment here, am limited to J2SE 1.4).
Why would a character not have a numeric
value? In other words, under what circumstances is
the -1 returned?I think you're misconstruing the meaning of "numeric value" as it's intended here. Numeric value just means that "3" has a numeric value of 3, "7" -> 7, and so on. It doesn't mean that characters like '%', '(', etc. have a numeric value. From the API:
Returns the int value that the specified Unicode character represents. For example, the character '\u216C' (the roman numeral fifty) will return an int with a value of 50.
The letters A-Z in their uppercase ('\u0041' through '\u005A'), lowercase ('\u0061' through '\u007A'), and full width variant ('\uFF21' through '\uFF3A' and '\uFF41' through '\uFF5A') forms have numeric values from 10 through 35. This is independent of the Unicode specification, which does not assign numeric values to these char values.
If the character does not have a numeric value, then -1 is returned. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.
To get the Unicode value of a char, just cast to an int as previously shown by DrClap (and myself, though less clearly so).

How get English Charactor unicode value?

I try to get charactor uni code value using following code. That code work for any other code excluding english.
When i put english charactor it does not get unicode value. As a charactor it get charactor, but I insert Other charactor it get unicode value as char value.
String temp = ;
temp = temp.substring(1, temp.length());
int temp_i = Integer.parseInt(temp, 16);
Char c_UCPoints = (char) temp_i;English Input:
temp = "\u002e"
c_UCPoints = "." ---- but i want to get "\u002e"
Tamil Input:
temp = "\u0b89"
c_UCPoints = "\u0b89" ----it show corect result
Any one how to get that unicode value. reply this.

You mean you want to manually convert to and from Unicode escapes? Try this: public class Test
public static void main(String... args) throws Exception
    String chEsc0 = "\\u002e";
    char ch = (char) Integer.parseInt(chEsc0.substring(2), 16);
    String chEsc1 = String.format("\\u%04x", (int) ch);
    System.out.printf("%s => '%c' => %s %n", chEsc0, ch, chEsc1);
} output: \u002e => '.' => \u002e

Problem with getting unicode values from console

Hi,
In my application I am passing unicode value like \u00DF from console. and writing this string value to a utf8 file. But in the file the value is printed not the actual unicode character.
Where the things are getting wrong.
I have declared a string in java like ;
String abc = "\u00DF";
and printed this to a utf8 file, it works fine and the corresponding unicode character for \u00DF is printed.
Why the unicode value passes from console is not working property. How can i resolve this ?
Thanks in advance...


And how are you putting it into the console in the first place?

How to display unicode values in file to corresponding characters

Hello Java-ians !
Could you please calrify my doubt ! I am able to generate unicode values for arbic, russian characters. I did it by generating a UTF-8 format file and I used native2ascii tool to generate unicode values. No I am unable to dispaly the characters. I read the file using FileReader and used JTextFiled.setText method to redisplay the characters. Instead of displaying the corresponding character, I am getting only unicode values. Why it's happening ?
Also could you plese tell me how ResourceBundle works ? It reads the unicode values and displays proper charcters, how ?
Please help me ! I need it desperately !
Martin Sunder Singh D.S.

you have to do like this:
FileInputStream fos = new FileInputStream(new File("japanies.out"));
BufferedReader bw = new BufferedReader(new InputStreamReader(fos,"UTF8"));
System.out.println(bw.readLine());
bw.close();

ADFS Active Authentication SAML token with unicode values throwing error when post to _trust end point in SharePoint

Hi All,
I have a SP2013 environment which authenticate users using ADFS 2.0 via Windows AD. We have two separate clients, Portal and Mobile. Portal users Passive Federation where as Mobile client uses Active Authentication with usernamemixed endpoint in ADFS.
I have an AD property which stores Unicode characters. In Active Authentication via Mobile, for a user who has a Unicode value in the AD property, I can get the SAML token successfully from ADFS.
Ex : <saml:AttributeValue>español</saml:AttributeValue>
However, when I post this SAML token to SharePoint _trust endpoint, I'm getting an error "500 Internal Server error". However for the same user, if I change the AD property value from "español" to "English" then I can get the FedAuth
cookie successfully from the _trust endpoint.
Also, for the same user, If I logged in via Portal which uses Passive Federation, then it's working fine.
Really appreciate your thoughts on this.
Supun

Hi Supun,
As you mentioned, the issue only happens in Active authentication. Would you please let me know which mobile client your users are using for the Active authentication, is it a custom one? Please be noted if you use a mobile browser, the authentication will
also be Passive.
In Passive mode authentication, STS also uses POST to pass the security token to the relaying party. I'd like to know what kind of tool you are using to post a SAML token to SharePoint endpoint as impersonation of an Active authentication. Since the Active
authentication flow is quite complex, I also suggest you to check the event log in your ADFS server, and try to find more information about the issue.
Thanks,

Unicode values of characters

hi friends
i want to find out unicode values of all characters present
in a string. has somebody witten any code for this?
the string is in japanese characters.
thanks for ur help (in advance)

This is extremely un-advanced. Just get a character
from the string and cast it to an int. That's the
Unicode value.What do you mean by un-advanced? Shouldn't you know what you get and what you cast into?

Unicode value of invisibles

Hi,
I have an XML file that contains an invisible, which when imported to Indesign CS turns into a Soft Return.
How can I determine the Unicode value of that character in the XML file?
Problem being, if I create a new XML file and use "\n" as my Soft Return character it becomes a Hard Return when imported.
Bye
SteveH

Easiest way would be to load the file into a hex editor, I think.

How to call VC++ dll whiich return char[] data type value in powerbuilder

Hi Everyone,
I am using PowerBuilder 11.1 build 8123.
I am calling VC++ DLL in our PowerBuilder application which return char[] data type value.
I just declare Global External Function:-
     Function char getOSSectionName() library "DocServClient.dll" alias for "getOSSectionName;Ansi"
And then call this function in window as:-
     Char      ls_section[1] = 'DOCAPPLICATIONS9X'
     ls_section[1]=getOSSectionName()
When I check ls_section[1] value in messagebox it display a symbol (please check attached attached image.)
VC++ function and return variable declaration:-
     __declspec(dllexport) char * __stdcall getOSSectionName()
       char    SectionName[_MAX_PATH];
Please let me know that my code is valid or not.
Please help..

Hi,
Thanks to Everyone for your suggestions.
I am solved my problem to change VC++ function as :-
     Int __declspec(dllexport) __stdcall getOSSectionName(char* SectionName)
                    instead of
     __declspec(dllexport) char * __stdcall getOSSectionName()
and declare global function as:-
       Function int getOSSectionName(Ref char ls_section[100]) library "DocServClient.dll" alias for "getOSSectionName;Ansi"
and call function in window as:-
     int li_ret
     char ls_section[100]
     string ls_sec
     li_ret=getOSSectionName(REF ls_section)
     ls_sec=ls_section
Thanks,

Character Unicode Value

Is it possible to have a VB script return the unicode values for a given range of characters in a paragraph or story?

We tried it on a 8.1.7 database and I was not able to reproduce
the error.
Here is how I insert and retrieve the data:
OraclePreparedStatement ps =
(OraclePreparedStatement) conn.prepareStatement
("insert into tab01 values (?)");
ps.setString(1, "\u2018");
ps.executeUpdate();
ps.close();
ResultSet rs = (conn.createStatement()).executeQuery("select col01
from tab01");
while(rs.next())
String str = rs.getString(1);
System.out.println("COL01 is "+str);
showUnicode("COL01 (Unicode Value) is "+str);
(conn.createStatement()).close();
conn.close();
And here is the result from the database:
SQL> select dump(col01, 16) from tab01;
DUMP(COL01,16)
Typ=1 Len=3: e2,80,98
Are you using thin driver or oci driver?
If oci driver is used, NLS_LANG needs to be set correctly and
the Client OS code page must support these characters. Hope this
helps.

Transfer a char type varialble value to NUMC type variable

Hi all,
I have a BSEG-PROJK type NUMC(8) variable and one xyz type CHAR(50) variable.
I have to pass value from xyz to BSEG-PROJK
my e.g is that while I am passing
xyz= 'M-000064'
BSEG-PROJK = xyz
then the value of BSEG-PROJK is 00000064 but i need M-000064

Hi,
The value M-000064 is showing in field PROJK of BSEG, due to the conversion routine ABPSP attached in the domain level of this field.
- To check the actual value stored in data base level
- SE16 Give table name=>to see the table contents Press F7=>settings=>user parameters=> uncheck the check box check conversion exit.
- now the value in field PROJK will show in numeric.

DKS
