get ascii code from string in xcode for iphone app

hey just a couple quick noob questions about writing my first ios app. Ive been searching through the questions here but they all seem to address questions more advanced than mine so im getting confused.

PHP from quotation mark output

I use a similar form on a regular basis and have just become aware that whenever a single OR double quotation mark is inputted into the form the output to myself (through email) displays the quotation mark as the ASCII code so \' with a backslash ive looked around and dipped into unique character encodings specialentities but cant seem to find anything that will help output it as a normal quotation mark.
