I have a situation where I have a series of character codes stored in the
database. In some cases they are the ASCII value of the character, in other
cases they are the > 127 character code value that you use in combination with
the ALT key to enter special characters into a document (e.g. ALT+0147 and
ALT+0148 get you 'smart quotes').
I'm trying to figure out how (or if it's possible) to obtain the Unicode
equivalent of the character code.
I've tried several variations of the following but so far none of them have
worked:
byte charCode = // get value from datatable
Encoding.ASCII. GetString( new byte [] { charCode } );
I also tried simply casting the charCode as a char, but of course that results
in a character using the charCode as a Unicode value, which gets me the wrong
character.
I found an example in JScript that does exactly what I want, but I'm writing in
C#. I only bring this up because it shows me that what I want to do is at least
possible, which leads me to believe there must be a way to do it.
Basically, I'm looking for an equivalent to the JScript charCodeAt method: http://msdn.microsoft.com/library/en...charcodeat.asp
Any suggestions?

Hi Craig,
Didn't you try to get that char codes as "char" or "string"?
You can also try "Encoding.UTF8. GetString(...)" .
If you'll get this string then [index] should do the job.

I *think* you're after Encoding.Defaul t.
However, the database really ought to be able to know how it's stored
them and give you the text in Unicode. What's the type of the column,
what's the database in question, and how are you retrieving the

The database has stored the value as an integer. The database isn't storing the
character, it's storing the character code (i.e. it's not storing the smart
quote, it's storing 147 as an integer).
The database is SQL Server 2000 and my C# code is calling a stored proc that is
used to populate a DataTable.

So it's storing a character as the integer value in an ill-defined
encoding? That doesn't sound like a terribly good idea, to be honest.
Anyway, Encoding.Defaul t *might* do what you want it to, as I said
before - just put the integer value into a byte array as the sole
value, and call Encoding.GetStr ing to get the appropriate string. If
the encoding is subtly different though, you'll have problems.

Is this possible in PHP? If so, can you please provide a short code snippet.
