Problem in extracting a value from textbox

Hi all,
I have the following field in the document I am trying to read through form extractor. I am setting it as bool inside the taxonomy but every time form extractor reads it as Yes. Also, I have set the recommended setting for No too in the template. When I have a look over the text file, the value extracted was this, in case of both Y or N, “☒”. Help!!
