Unescaping hex encoded characters in string?

ruby-talk
1

If I have a string like "Don\x{2019}t Let Me Fall"

How do I unescape the hex encoded characters, in this cae convert the
string to "Don't Let Me Fall"

2

In Ruby 1.9.* something along the lines of

str.gsub /\\x\{(\h{4})\}/ do |code|
  code.to_i(16).chr(str.encoding)
  # code.to_i(16).chr(Encoding::UTF_8)
end

Or use gsub! for inplace modification of the string. You might have
to twiddle with the encodings. Please see

Kind regards
