GIAS publishes its CSVs in Windows-1252 and sends no charset. The tap read resp.text, so requests guessed the codec, and the encoding="latin-1" passed to read_csv did nothing on already-decoded text. On 3 Oct 2026 the guess was windows-1250, and "St Thomas à Becket" (138950, 149557) was stored as "St Thomas ŕ Becket". A different guess on another day would garble other accented names. Both streams now decode the downloaded bytes themselves (gias_csv.py). A byte Windows-1252 leaves undefined becomes U+FFFD with a logged warning instead of failing the load, so one odd name cannot stop the daily refresh. None of the nine extracts checked (1 Jul to 3 Oct 2026) contains such a byte. Checked by running the tap on the real 3 Oct extract with .text forced to windows-1250: all 52,586 rows decode, with no "ŕ" and no replacement characters.
