  {gsm_coder, ".*", {git, "https://github.com/silviucpp/gsm_coder.git", "master"}},
}.

gsm_coder:utf8_check_gsm7(<<"abcdef">>).
true

gsm_coder:sms_text_parts_number(<<"abcdef">>).
1

gsm_coder:utf8_to_gsm7(<<"abcdef">>).
<<97,241,152,92,54,3>>

gsm_coder:utf8_from_gsm7(<<97,241,152,92,54,3>>).
<<"abcdef">>

gsm_coder:utf8_to_gsm8(<<"abcdef">>).            
<<"abcdef">>

gsm_coder:utf8_from_gsm8(<<"abcdef">>).
<<"abcdef">>

Tests

In order to run the tests just use rebar3 ct from project root.
