Ruby中的GSM-7转换和七进制编码库？

我正在寻找一个纯Ruby的解决方案，将UTF-8转换为GSM-7并返回，并在此过程中进行七位编码/解码。
这里的背景是：通过网关和REST请求发送和接收SMS。
我用libiconv（http://mobiletidings.com/2009/07/06/gsm-7-encoding-gnu-libiconv/）找到了一个解决方案（它或多或少可以工作，但由于某些缺陷，它不被libiconv本身接受）。
我更喜欢一个纯Ruby的解决方案，最有可能的是一个用于转换的查找表和一个7-8位编码器来处理产生的七位字节。
有人已经做过了吗？有什么建议吗？
谢谢你汤姆

我正在寻找完全相同的（转换UTF-8到GSM 03.38），但一无所获。所以我写了一个小转换器：

require 'iconv'

class String

  # Returns a new string in GSM 03.38 encoding
  def to_gsm0338
    latin1_to_gsm_map = Hash.new
    GSM0338_MAP.each_slice(2) { |gsm_symbol, latin1_symbol| latin1_to_gsm_map[latin1_symbol] = gsm_symbol }
    Iconv.iconv('ISO-8859-1', 'UTF-8', self).first.unpack('C*').collect { |utf8_symbol| latin1_to_gsm_map[utf8_symbol] }.flatten.pack('c*')
  end
end


# Test
if $0 == __FILE__
  puts "[ÖÄÜöäü]~|-_".to_gsm0338.inspect
end

我现在可以用ruby通过sms_client（smsclient.org）发送短信：

system "sms_client 0123456789 '#{msg.to_gsm0338}'"

我知道这是一个老问题，但我一直在寻找一个解决方案.我发现了一个宝石，是工作良好，我认为：https://github.com/livebg/smstools
我在Rails 4和Rails 5中都使用了它。
