 * `matchPos`: `"start"` or `"any"`: whether to match the text entered at the start or any position in the option value
 * `matchProp`: `"label"`, `"value"` or `"any"`: whether to match the value, label or both values of each option when filtering
 * `ignoreCase`: `Boolean`: whether to ignore case or match the text exactly when filtering
+* `ignoreAccents`: `Boolean`: whether to ignore accents on characters like ø or å
 
 `matchProp` and `matchPos` both default to `"any"`.
 `ignoreCase` defaults to `true`.

 #### Advanced filters
 
 You can also completely replace the method used to filter either a single option, or the entire options array (allowing custom sort mechanisms, etc.)
 
-* `filterOption`: `function(Object option, String filter)` returns `Boolean`. Will override `matchPos`, `matchProp` and `ignoreCase` options.
-* `filterOptions`: `function(Array options, String filter, Array currentValues)` returns `Array filteredOptions`. Will override `filterOption`, `matchPos`, `matchProp` and `ignoreCase` options.

 For multi-select inputs, when providing a custom `filterOptions` method, remember to exclude current values from the returned array of options.
