golang invalid character 'ï' looking for beginning of value

This error message usually occurs when you have a non-ASCII character in your code, such as the character ï. Go uses UTF-8 encoding, so if you accidentally include a character that is not part of the UTF-8 character set, it will result in this error.

To fix this error, you should check your code for any non-ASCII characters and remove them. You can use a text editor that supports UTF-8 encoding, such as Notepad++, to identify and remove any non-ASCII characters. Alternatively, you can try saving the file in UTF-8 encoding and see if that resolves the issue.

If you are still having trouble, you may want to check the encoding of any files that your code is importing, as these could also contain non-ASCII characters that are causing the error.
