City search fails to match characters without the accents
When searching for a city to add a new world clock, the search field fails to match unaccented characters to the equivalent accented terms in the city database.
Example: Typing "Zurich" (with a simple 'u' instead of the accented 'ü') in the search field fails to return any results.
Expected behavior: Searching "Zurich" should match it to the option "Zürich Switzerland".
