Incorrect behaviour with spezial character (ÖÄÜ)

[Günter Rudigier]

Hi there

I guess I have found an other bug in Autocomplete control. If I have items inside with German special character, the compare is not correct. If i press 'MA' and have items with 'MÄ' and 'MA' both are shown. My expected behavior would be to only find 'MA' items, isn't it?

Hi Günter Rudigier,

We’ve reviewed the reported issue regarding diacritic search in the SfAutoComplete control. By default, diacritic-sensitive search is not supported in the Syncfusion MAUI Autocomplete control. However, this can be achieved through custom filtering.

 

To address this, we’ve implemented a custom filtering behavior using StringComparison.OrdinalIgnoreCase. This approach ensures:

• Only exact character matches are considered.
• Special characters like Ä, Ö, and Ü are treated as distinct from A, O, and U.

 

For your reference, we’ve attached a sample and a video demonstrating the solution. Kindly test it and let us know if this resolves your issue.

 

Regards,

Manju D
