Count and detect if characters are GSM or UNICODE

[viktorsmari]

Does, or can this ruby library include the same (or similar) method to detect if SMS characters are GSM or UNICODE encoding?

As seen at the bottom of this page:
https://www.plivo.com/docs/sms/concepts/encoding-and-concatenation#unicode

It is very useful.
We would like to use it in our app, so our clients can know how many SMS they will be sending.

@viktorsmari This feature has not yet been implemented. Our developer @narayana-plivo has created a function that allows you to return your requirements. Please use the code below for now. We'll try to include this in a future release.

require "plivo"
include Plivo

def get_unit_count_encoding(text)
      unit = 1
      mx_unsplit_len = 160
      mx_part_len = 153
      count = text.size
      if text.force_encoding("UTF-8").ascii_only?
        encoding_type = "GSM"
      else
        encoding_type = "UNICODE"
        mx_unsplit_len = 70
        mx_part_len = 67
      end
      if count <= mx_unsplit_len
        return unit, count, encoding_type
      end
      charcount = text.size
      while text.size > 1
        if text.size > mx_part_len
          text = text[mx_part_len..charcount]
          unit += 1
        else
          text = ''
        end
      charcount = text.size
      end
      return unit, count, encoding_type
    end

text = "Hello, this is a sample text"
units, count, encoding_type = get_unit_count_encoding(text)
puts units, encoding_type, count

api = RestClient.new("<auth_id>", "<auth_token>")
response = api.messages.create(
  src: "<source_number>",
  dst: "<destination_number>",
  text: text,
)
puts response
