Description

=begin
There may be a bug in the CSV module. I found it impossible to set the backslash as quote_char, trying so gives the following:

1.9.3-p392 :055 > out = CSV.new($stdout, quote_char: "\")
RegexpError: premature end of char-class: /[][]/

I tried using Regexp.escape, too, but no luck:

1.9.3-p392 :060 > out = CSV.new($stdout, quotechar: Regexp.escape("\"))
ArgumentError: :quote
char has to be a single character String

Is this expected behaviour?

I'm not sure if it's related, but here the internal and external encodings:
1.9.3-p392 :061 > Encoding.defaultexternal
=> #Encoding:UTF-8
1.9.3-p392 :062 > Encoding.default
internal
=> nil

=end

Actually, I mistook quotechar for escapechar. Setting a backslash as quote_char is probably not a desired feature. I was looking for a way to escape double quotes differently than using two double quotes. Sorry for the noise.
