ASP.NET 2.0 website fails on open - unable to translate Unicode character

-I don't think this is beacuse of demo thing, it's really different.

-in this page:
http://msdn2.microsoft.com/en-us/library/system.text.encoderexceptionfallback.aspx

I found these lines:
"However, an encoding operation can fail if the input character cannot be represented by the encoding. For example, an ASCIIEncoding object cannot encode a character whose Unicode code point value is outside the range U+0000 to U+007F. "

-Do you use latin-only in your databases?
-Does your mdb filename has any non-latin characters?

- Does your project files names in latin-chars ?

If possible, give us the line where this error occured to discuss further.

Nehaya

Nehaya,

Thank you for your response. The access mdb is named Current Data.mdb and the data in it does not contain non-Latin characters. The full text of the error message is:

Nehaya,

The problem was in the data - it contained numerous unprintable characters. After editing them out the site opened properly. Many thanks.
