lua json cjson Lua

I'm attempting to set up This might be a silly question, but I'm trying to debug I'm collaborating on a project where I'm working on a project and hit a roadblock. I'm working on a Lua script that processes JSON data using the cjson library (version 2.0.4). I encountered an scenario where certain JSON strings containing unusual characters, like emojis or special symbols, are failing to parse, resulting in the following behavior: ``` behavior: cjson: invalid UTF-8 string ``` Here's a snippet of the code I have: ```lua local cjson = require 'cjson' local jsonData = '{"name": "Alice 😊", "age": 30}' local function parseJSON(data) local success, result = pcall(cjson.decode, data) if not success then print("Failed to parse JSON: " .. result) return nil end return result end local parsedData = parseJSON(jsonData) if parsedData then print(parsedData.name, parsedData.age) end ``` I'm using Lua 5.4.3 and the script runs fine for standard JSON strings without unusual characters. I've tried encoding the string to UTF-8 before parsing, but I still get the same behavior. I've also confirmed that the input JSON is valid using external validators. Is there a way to make cjson handle these characters correctly, or should I switch to another library that better supports UTF-8? Any help would be appreciated! My development environment is macOS. Thanks in advance! I'm coming from a different tech stack and learning Lua. Has anyone dealt with something similar? For reference, this is a production microservice. I'm open to any suggestions. For reference, this is a production desktop app. Am I approaching this the right way? I'm working on a desktop app that needs to handle this. Am I missing something obvious?
