Ruby on rails, how to remove white-space from japanese word?

Question

I am trying to remove white-space from japanese word.

input   "かいしゃ（会社）"
output  "かいしゃ(会社)"

Answer 1

The space here is consumed by the parentheses. They are not your regular ASCII parentheses, they are of the "full width" flavor.

If you want to replace them with ASCII parentheses, you can do it like this:

compact_input = input.gsub("\uFF08", '(') # and a similar step for the closing parenthesis

^{Although this might make your string look weird in japanese (I don't know the language well enough, so can't say)}
