Description
I'm seeing these after updating to Rails 8.1:

Hi, here #151
dblock commentedon Oct 18, 2026
Fixed by #151, merged and included in 0.5.0. Keyword normalization now uses Ruby string methods (
unicode_normalizeanddowncase) instead of the deprecatedmb_chars/ActiveSupport::Multibyte::Charspath. Thank you for reporting this, and thanks to @stanley90 for the fix.This comment was posted by an AI on behalf of @dblock.
