in reply to Replace only selected characters

Howdy!

Instead of answering directly, I ask you to consider what the "g" and "i" flags do. Think carefully about everything your search expression actually says. Do the parts work together the way you want them to?

Try carefully applying your replace manually. Alternately, express more clearly what you are trying to accomplish with your replace.

yours,
