atr_latin_to_hebrew_key.php

/*
* Tired of typing a search term in my cooking blog just to find that I typed in Latin keys instead of Hebrew. See here https://yehuda-tiram.com/
* This code will replace every Latin character in WordPress search textbox with its Hebrew equivalent.
* The const hash can be changed to any language as needed.
* The search textbox element document.getElementsByName('s') can be changed to anything else.
