UTF-8 to ASCII Conversion

UTF-8 to ASCII Conversion

does anybody knows how to convert from UTF-8 to ASCII.

the problem is that,the DB supports UTF-8 in one server, which can display Special characters when PRAWN generates the PDF... when the same code is migrated to another server which supports ASCII- database, its not working. so is there any method or code that tells the server to convert or process in the same UTF-8 type.

Helppppppppppppppppppppp!!!!
