Type of encoding for barcode for Symbol VS 6608 scanner

Question

Hi All,
Which type character encoding should use in PDF design in live cycle designer for the decoding barcode using Symbol VS 6608 scanner.
I have used UTF8 as character encoding but didn't get proper decoder output for Russian languages. I do get proper response for English characters.
Do adobe live cycle designer supports windows 1251 character encoding for paper forms barcode?
I couldn't get any option of windows1251 in the list supported character encoding in live cycle designer for paper forms barcode.
Is there any alternative character encoding which I can use from the list of encoding present in designer as a proper replacement for windows 1251 character encoding?
Regards
Abhishek

If it is a T-SQL problem you want help with, you should use the T-SQL forum. This is the forum for using .NET inside SQL Server.
The answer to your question is probably, but the spec is unclear. If you know that there are always four character in front of the barcode, and the code you are looking for is always 13 characters (which they seem to be in your sample data) you
can do:
Calcomp LIKE substring(@barcode, 5, 13)
This permits the use of an index on the Calcomp column to be used, why the lookup is quick.
If the prefix can be any length, or the Calcomp can be, you can do:
@barcode LIKE '%' + Calcomp + '%'
but this will result in a scan of the entire table, so it is far less efficient. There is also some risk for multiple hits.
Thus, if you can determine from the barcode directly, the possible code(s) to look for before you start searching, this can be both more efficient and safer.
