unicode

Hi all,

I am trying to make my web app compatible with international languages and I am stuck with trying to convert escaped characters in my Delphi .NET DLL.

The front end code is passing the UTF-8 hex notation with an escape character e.g for ? I pass \uE3818A. In my DLL I capture this and constract the following string '$E3828A'. I need to convert this back to ? and send it to my database, I've been trying to use Encoding.UTF8.GetBytes and Encoding.UTF8.GetString but with no luck.

Anyone could help me figure this out?

Thank you.

Consider the following problem: A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1.

How can I tell if a CSV is in UTF-7 or UTF-8

Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option). Using .NET… >>> More
