Demonstrates how to convert a string to the GSM character set. For more information about the GSM character set, see GSM Character Set Lua

local chilkat = require("chilkat")

-- Demonstrates how to convert a string to the GSM character set byte representation.

local s = "support@chilkatsoft.com, {abc}"

-- In the above string the a-z letters have the same 1-byte values in the GSM character set.
-- The '@' character is the 0x00 byte in GSM.
-- The curly brace chars are 2-bytes each in GSM -- each beginning with the 0x1B escape char.
-- The '.', ' ', and ',' are the same in GSM as us-ascii.

-- Let's convert to GSM.

-- bdGsm will contain the GSM bytes.
local bdGsm = chilkat.BinData.new()

-- Append the string to bdGsm.  The 2nd arg "gsm" tells AppendString to
-- convert the incoming string to the gsm byte representation.
local success = bdGsm:append_string(s, "gsm")

-- Let's examine what we have in hex:
print(bdGsm:get_encoded("hex"))

-- The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

-- Save the GSM bytes to a file.
success = bdGsm:write_file("qa_output/gsm.txt")
