I finally researched an issue I was having with finding tab, new line, carriage return characters at the beginning of the line. I have an automated SQL procedure to create product data feeds in a tab delimited format. One of the symptoms of a soft SQL failure is that the line will wrap. This situation can be detected by looking for a first character that is either a tab, new line, or carriage return using the regex expression ^[\t\n\r]. . The simple find/replace does not find the problem lines while the Advanced version works as expected.
