Render pdf file with errors: Invaild Char etc

Rails
1

Hello G.s,

I write some codes to render a pdf file into a view page. For some
pfd file, they works fine, while others files got different errors. The
errors are like:

Invalid char `\XXX' in expression,  OR
unexpexted tCONSTANT / tIDENTIFIER, expecting 'XX' ...

Do you guys have any idea how to get ride of these errors?

--> Here is my action:

def show_pdf
respond_to do |format|
format.pdf do
render :file =>params[:pdfName]+’.pdf’, :layout => false
end
end
end

--> Errors in Log file:
