Hexdecimal to String Convert - Ruby

I'm trying to convert hexadecimal to string using Ruby and it does not work with some Chinese characters. I am new to Ruby.

Current code is working fine with non-Chinese characters but now code needs to support Chinese characters. It converts HexDecimal to string using ISO-8859-1 and UTF-8 encoder:

extractpayload = "e5b7b2e5ae8ce68890e38082e68891e4bbace5b086e59ca8e5aea1e6a0b8e5b9b6e7a1aee8aea4e8aea2e58d95e5908ee58f91e8b4a7efbc8ce5b9b6e7ab8be58db3e4bba5e79fade4bfa1e5bda2e5bc8fe9809ae79fa5e682a8e3808220e69fa5e79c8be8aea2e58d95e4bfa1e681afe68896e7aea1e79086e794b5e5ad90e58f91e7a5a8";

gettransformedfullpayload1 = [extractpayload].pack("H*").force_encoding("ISO-8859-1").encode("UTF-8");

It's already hex-dumped UTF-8.

str = "e5b7b2e5ae8ce68890e38082e68891e4bbace5b086e59ca8e5aea1e6a0b8e5b9b6e7a1aee8aea4e8aea2e58d95e5908ee58f91e8b4a7efbc8ce5b9b6e7ab8be58db3e4bba5e79fade4bfa1e5bda2e5bc8fe9809ae79fa5e682a8e3808220e69fa5e79c8be8aea2e58d95e4bfa1e681afe68896e7aea1e79086e794b5e5ad90e58f91e7a5a8" => "e5b7b2e5ae8ce68890e38082e68891e4bbace5b086e59ca8e5aea1e6a0b8e5b9b6e7a1aee8aea4e8aea2e58d95e5908ee58f91e8b4a7efbc8ce5b9b6e7ab8be58db3e4bba5e79fade4bfa1e5bda2e5bc8fe9809ae79fa5e682a8e3808220e69fa5e79c8be8aea2e58d95e4bfa1e681afe68896e7aea1e79086e794b5e5ad90e58f91e7a5a8"
[str].pack('H*').force_encoding('utf-8') => "已完成。我们将在审核并确认订单后发货，并立即以短信形式通知您。 查看订单信息或管理电子发票"
