If you want to exclude specific characters, you would have to explicitly state which ones. You can use this web page :- http://www.theasciicode.com.ar/extended-ascii-code/capital-letter-a-ring-uppercase-ascii-code-143.html to see which character code belongs to each character. As you can see in this page, the characters you mention are between 128 and 165 . So just add: && ((charCode > 128) && (charCode Recommendation : To exclude all non-English characters, you can replace your whole condition with this simple one: if (charCode > 126) { swal( "Enter Only Character" ); return false ; } To exclude all non-English characters and allow Å Ä Ö å ä ö : if ((charCode > 128) && (charCode != 134) && (charCode != 142) && (charCode != 143) && (charCode != 153) && (charCode != 199) && (charCode != 198)) { swal( "Enter Only Character" ); return false ; }
