<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I just knew this non printing character stuff was going to come back and bite me…<o:p></o:p></p>

<p class="MsoNormal">I can identify the rows with non printing characters excluding \t, \r and \n.<o:p></o:p></p>

<p class="MsoNormal">The data in question is a long varchar. But (fortunately) the longest item is under 12000 characters, so we are under the 32000 char varchar conversion limit.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The easiest way I can think of doing this is to do it in a database procedure…<o:p></o:p></p>

<p class="MsoNormal">The data was probably added to a web form via a cut and paste from a word document, so we’ve picked up things like smart quotes. Hence we may ultimately be interested in replacing multi character sequences with simple ansi equivalents.
I have a suspicion a clean() function is galloping in my direction.<o:p></o:p></p>
