Apostrophe and accent letters cannot be used in Live Search queries

Live Search cannot handle any queries that contain apostrophe or accent letters. These accent letters are frequently used in product names of French and/or other European origin.

See screenshots below, the query of L'If returns no results, yet multiple versions of the product exist and are visible when queried by SKU.

Identical failure to return Live Search results occurs when queries include accented letters such as â, î, é, è ...

Start by reproducing the Live Search failure with `L'If` and accented letters such as â, î, é, and è, then compare those queries with the SKU search that returns the products. Done means Live Search returns the matching product variants for apostrophe and accent-letter queries; the issue names no files or tests to inspect.
