Steps to reproduce:
- visit http://hu.wikipedia.org
- type "kurtvirag" in the search box
Expected: [[hu:Kürtvirág]] is suggested
Actual: no suggestions
This is particularly problematic because people often don't have access to the right type of keyboard, and have only very inconvenient ways of entering characters with diacritics. On mobile, entering diacritics is inconvenient even when the keyboard is set up correctly.
The old behavior was to drop all diacritics for indexing, which was not great, but better than the current one.
The ideal behavior would be to index both the exact and the stripped title, and give more weight to the first; so search suggestions with different diacritics would not crowd out better matches but would still appear if there is no perfect match.
