How do I find (Unicode: 0x1) using notepad++ (unicode to char range)

Question

I keep getting this exception in the logs Parsing error, line 1230, uri null An invalid XML character (Unicode: 0x1)

sadly I don't have access to the actual xml and the entire xml is printed in a single line as part of the stackchase

how do I use notepad++ to search for Unicode 0x1 ?

I read that one can search using notepad++ character range. and 0x1 can be convert to char range.

Can someone explain to me how to conver it?

Solution

Set search mode to Regular expression and search for \x01.

Note that you didn't specify which Unicode character encoding this is (UTF-8, UTF-16, etc.). If you open the log file in wrong encoding, search might not work. This could happen if your xml file and log file have different encodings.
