Amen brother.

I use three different schemes every day:
1. Java
2. Funduc search replace
3. Visual Slick edit Unix

It is so hard to remember six different sets of reserved characters,
just to get started.  I wrote a little tool to help
http://mindprod.com/applet/quoter.html

It takes any string and treats it as data and quotes it
by the three different schemes, search  or replace.
and shows it raw, in a Java String, in a CSV file.

I was browsing http://regexbuddy.com

Their products supports many different schemes.  I asked about the
three I use. They did not respond.

I have written a specialized CSV-based regex search/replace.  I like
working with Java regexes best since they are rich in features, and
well documented.

It takes lines of the form

fromString, toString, file1, file2, file3...

At some point I will teach itn wildcards and negatives.
