RE: UniversalString throws exception

Joe---
I found a smal prob may be iam wrong. Just correct mine

Wheni use the statement  ustr.set((const char *)&ich[0]); i am able to
retrive only the first character "L" in och
But when i use the same assignment as ustr = &ich[0]; i am able to retrieve
the entire string "Lé Royal Meridian"

Is that so. Is there any way i can convert UTF8 to ascii i..e wchar_t to
char * and then use ustr.set()
Pre thanks for the timely help.

Regds

Siva and Kaliraj,

Our code is actually working as intended.  The reason you are failing is
because you are not giving the set function the string in correct utf8 form.
To solve this, I have provided you with the correct code below with a few
inline comments describing what has been changed and why.

int main()
{
 UniversalString ustr;
 
 /* 	This must be declared as a wide character array and, when assigning
a     	wide character string, the L must be added as a qualifier before the
first  double quote 
  */
 wchar_t ich[32]= L"Lé Royal Meridian";

 /* 	This should be a character pointer because the getAsUTF8 function
returns a strdup'd copy of the UTF8 string.  Since memory is already
allocated, it is unnecessary to allocate extra space.  This would
leave room 	for a potential memory leak.
  */
 char* och = NULL;
 
 try
 {
   ustr.set((const char *)&ich[0]);
   och = ustr.getAsUTF8();  /* see comment above where och is declared */
 }  
 catch(SnaccException &se)  
 {
      se.getCallStack(std::cout);
      cout << "Exception thrown Snacc " <<se.what()<< endl;  }
catch(exception &e)  {
      cout << "Exception thrown : " <<e.what()<< endl;  
 }  
 
   free(och);

   return 0; 
}

Thank you for asking this question as I'm sure that you guys aren't the only
ones who have ever come across this issue.  I hope this solves your problems
and assists you in further devolopment.  Please let me know if I can do
anything else for you.

--Joe

Joe,

I have installed the patch and tried again.
I am getting the same error (Only the error code is changed from 665 to
688). 

I have given below the piece of code I tried:
int main()
{
 UniversalString ustr;
 char ich[32]="Lé Royal Meridian";  
 unsigned char och[32];
 
 try
 {
  ustr.set((const char *)&ich[0]);  
  strcpy((char *)&och[0],ustr.getAsUTF8());
 }
 catch(SnaccException &se)
 {
   se.getCallStack(std::cout);
   cout << "Exception thrown Snacc " <<se.what()<< endl;
 } 
 catch(exception &e)
 {
   cout << "Exception thrown : " <<e.what()<< endl;
 }
 return 0;
}

Output:
asn-stringtype.cpp 688 WideAsnString::set()

Exception Thrown Snacc Invalid UTF-8 string

Thanks,
Siva

Before I troubleshoot this problem, I want to make sure that you have
the July 7, 2005 patch installed for eSNACC found here:

Importance: High


Hello,

I face a problem with eSNACC (I am using version 1.7).

The ASN throws some exception when I use French characters.
For example, there is one ASN data type called UniversalString.
When I try to store a value "ü" inside the UniversalString it throws an
exception saying "UTF8string invalid".
The storing procedure is the same. It works fine for all English
characters
but when try to use it for French characters like ü or ä like this it
doesnt
work.

Is there a possibility at the code generation time itself (while
generating
VNP_message set.cpp and .h from ASN.1) to make it support these
characters.

Kindly help

Thanks,
Siva
