@@ -53,6 +53,7 @@ New Multiple-Select Options:
   - `sanitizer` can be used to sanitize HTML code and prevent XSS cross-site scripting attacks (see [demo](https://ghiscoding.github.io/multiple-select-vanilla/#/options32)).
   - `showOkButton` to add an "OK" button at the end of the multiple select option list (see [demo](https://ghiscoding.github.io/multiple-select-vanilla/#/options25))
   - `showSearchClear` show a clear button on the search filter input (see [demo](https://ghiscoding.github.io/multiple-select-vanilla/#/options34))
+  - `diacriticParser` can be used to parse and normalize diacritic signs when filtering select list (accents) (see [demo](https://ghiscoding.github.io/multiple-select-vanilla/#/options35))
 
 ## CSP Compliance
 The library is now CSP (Content Security Policy) compliant since `v0.6.0`, however there are some exceptions to be aware of. When using any html string as template (with `textTemplate`, `labelTemplate`, `renderOptionLabelAsHtml` or `useSelectOptionLabelToHtml`), you will not be fully compliant unless you return `TrustedHTML`. You can achieve this by using the `sanitizer` method in combo with [DOMPurify](https://github.com/cure53/DOMPurify) to return `TrustedHTML` as shown below and with that in place you will again be CSP compliant.
