StringBuilder Encode Charset

Demonstrates the importance of the charset argument when encoding/decoding. Lua

local chilkat = require("chilkat")

local s = "é é é"

local sb = chilkat.StringBuilder.new()

sb:append(s)
sb:entity_decode()

-- The string now contains: "é é é"
print(sb:get_as_string())

-- If encoded to hex using the iso-8859-1 charset,
-- each é char is represented in 1 byte.
-- Output: E920E920E9
print(sb:get_encoded("hex", "iso-8859-1"))

-- If encoded to hex using the utf-8 charset,
-- each é char is represented in 2 bytes.
-- Output: C3A920C3A920C3A9
print(sb:get_encoded("hex", "utf-8"))

-- Here's utf-16
-- Output: E9002000E9002000E900
print(sb:get_encoded("hex", "utf-16"))

-- utf-32
-- Output: E900000020000000E900000020000000E9000000
print(sb:get_encoded("hex", "utf-32"))
