Accent Sensitivity in Omeka S Partial Match Search

Overview I investigated accent sensitivity in Omeka S partial match search, and here are my notes. Symptom For example, when items containing the string “tako” (in hiragana) are stored, searching for “tako” in hiragana, katakana, or with dakuten (voiced mark) variations all return the same results. Cause The issue appeared to be caused by the default collation “utf8mb4_unicode_ci” set during installation. Specifically, this collation is “case-insensitive” (does not distinguish between uppercase and lowercase) and “accent-insensitive” (does not distinguish between accented and unaccented characters), which is why hiragana, katakana, and dakuten variations return the same search results. ...
