Location filter not working with accents

Hello,

We’re using your plugin on a client website and we noticed a small bug in sanitization due to accents in location names.

The plugin version is 3.4.24

Example

Location name : Théâtre Cornillon

When filtering on this location on the main calendar page returns no events.

The problems seems to be the map_deep sanitize_text_field which is run on the $_GET array.

File : wp-content/plugins/my-calendar/my-calendar-events.php
Method : my_calendar_get_events
Line : 111

The result for this location is the name is truncated.
When filtering the name passed through GET parameter is Th%C3%A9%C3%A2tre+Cornillon

(MAIN_URL + /my-calendar/?ltype=name&loc=Th%25C3%25A9%25C3%25A2tre%2BCornillon)

After sanitization this name is transformed to Thtre+Cornillon which is not recognized.

For now i have edited the code to make it work by disabling sanitization, i know it’s not really good regarding security but it would be great if you could provide an update to the actual plugin to make it work.

Thank you.

Stefan.
