Subject: Re: Special characters in csv header using fastercsv

You are correct.
I need to check all my DB column titles.  I updated the column title and 
the next error was another DB column.

In your code...
:header_converters => lambda { |h| h.tr(" ", 
"_").delete("^a-zA-Z0-9_")},

what is happening here?
h.tr(" ", "_").delete("^a-zA-Z0-9_#")

it looks like you're checking a table row for an instance of " " and 
replacing with "_"
but I'm unsure of the ".delete("^a-zA-Z0-9_")"
