In my country, we're using Cyrillic characters, instead of Latin. Many people don't have Cyrillic keyboard on their devices so I decided to use a Latin to Cyrillic function so they can find their city in the Select2's dropdown. The function works, but does not replace the last written letter. When I write a few letters and delete the last one it works. Maybe the function is delaying and activates after Select2's search?
Here's the code:
