"un-meta" the control characters
A coworker just presented me with this task. I came up with two solutions, but I don't like either of them. He has a text document and wants to scan it for characters such as newline, tab, form feed, carriage return, vertical tab. If found, he wants to replace them with their typical representation (ie, \n, \t, ... 3 Nov 2009 23:48
