getting unreadable symbols using ruby-smpp

Question

I'm using ruby-smpp to send ussd requests, for now everything working fine with ISO-8859-1 symbols, except Cyrllic.

optionals = {0x0501 => Smpp::OptionalParameter.new(0x0501, '\u0011')}
send_mt("055012", "066012", "Привет", {optional_parameters: optionals, data_coding: 8})

submit_sm.rb

@short_message = short_message.encode("UTF-16BE").force_encoding("BINARY")

but anyway getting unreadable symbols, can it be the carrier issue?

p.s also tries this commit: https://github.com/kubum/ruby-smpp/commit/72eb124c45df962a5412f7a821ccb02cccdabe60, but no success

Answer 1

the USSDC with which i was working with uses data_coding: 72, someway. Resolved.
