What are encoding errors?

What are encoding errors ? Does XML do have encoding errors related to ASCII characters

Hello, simplyhuman!

You can get ther “An invalid character was found in text content” error if your XML contains non ASCII characters, and the file was saved as single-byte ANSI (or ASCII) with no encoding specified.

Yes it have errors in ANSI because it is restricted in conversion of spacial char but you can use UTF 8 to get rid of this problem.
