Original Request Description

I have a Python 3.11 import script that reads monthly CSV exports from a partner and loads them into SQLite, but it silently drops rows whenever the text includes non-ASCII characters. The odd part is that the job finishes cleanly and reports a normal row count, so I only noticed it when the database total kept coming up short. The missing records seem to cluster around names and notes with accents, em dashes, curly quotes, or occasional CJK text. Right now the script uses csv.DictReader, wraps most row handling in a broad try/except, and normalizes fields before insert. I suspect the issue is either an encoding/decoding problem, a bad errors= setting, or a branch that treats “unrecognized” text as invalid and skips the row.

I want help pinpointing the most likely failure mode, not just general Unicode advice. A good answer should explain why rows can disappear without raising an obvious error, show the specific code pattern that is risky, and suggest a safer import flow that preserves Unicode end to end. Please include a concrete fix in Python, plus a small test strategy or sample assertions that would catch this class of bug before the import reaches production. If there are multiple plausible causes, rank them and explain how to verify each one quickly.
