🔍 The Silent Error That Breaks Everything: UTF-8 vs UTF-16 Nightmare | AHK Hero Extract

Summary This video documents a technical debugging session where three developers troubleshoot a search tool that uses AI to match user queries with tagged DLL files. The main issue involves one version of the tool failing to return results despite running without errors, leading to a systematic code review and problem identification. Key Points *[00:00:00] - Tool Introduction and Discovery* • Team discusses two versions of a search tool - one that reads DLL files directly and another that uses extracted tag data • Connie created a "Claude approach" tool that searches for terms and lets the system decide which DLL files to search • Isaiah explains the original tool reads all DLL files, shows contents, and allows filtering on the read data • Joe mentions UI improvements made to the resource folder, specifically moving search functionality from "filter" to its own section *[00:08:31] - Code Analysis and Problem Identification* • Isaiah conducts a systematic code review, focusing on file encoding issues in the INI file reading process • Identifies that the code assumes UTF-16 encoding for INI files, but the actual file might be in UTF-8 format • Explains how encoding mismatches cause silent failures - the tool runs without errors but returns no results • Discusses potential issues with DLL calls, 32-bit vs 64-bit compatibility, and match scoring algorithms that could result in zero scores *[00:16:55] - Root Cause Resolution and Best Practices* • Joe confirms the encoding issue was the root cause - changing file read from UTF-16 to UTF-8 resolved the problem • Isaiah explains how INI files created manually (via VS Code) default to UTF-8, while AutoHotkey's IniWrite creates UTF-16 files • Team discusses the importance of explicitly setting file encoding at the script level to prevent similar issues • Conversation shifts to exploring vector-based similarity matching as an alternative to AI API calls for known tag sets Brief Summary The debugging session successfully identified file encoding mismatch as the root cause of the search tool's failure. The team learned valuable lessons about explicitly declaring file encodings and the differences between manual file creation and programmatic INI file generation, leading to discussions about more efficient alternatives to AI-based matching for static datasets.
