Ruby sanitize string: remove nonword-chars, but preserve dashes and underscores.
Raw
ruby-sanitize-string-remove-nonword-chars-preserve-dashes-and-underscores.rb
str1 = "11423!@#$!@_asdf+_1234__asfsdf"
str1.gsub(/\W/,'')
# => "11423_asdf_1234__asfsdf" (seems legit…)
str2 = "11423!@#$!@_asdf+_1234__asf-sdf"
str2.gsub(/\W/,'')
# => "11423_asdf_1234__asfsdf" (doesn't preserve dash)
str2.gsub(/[^-\w]/,'')
# => "11423_asdf_1234__asf-sdf" (profit!)
