Arabic Menu

I am getting an issue with Customizr’s menu once I use arabic, it separates the first letter from the word. This issue has apparently been discovered by others, all of who used the following CSS code. However that code did not work for me! any suggestions

/* Change menu/navbar padding: 2nd and 4th for horiz padding */
.navbar .nav > li > a {
padding: 5px 16px 5px 16px;
/* and change font size in menu */
font-size: 16px;
}

/* Change font size of first letters in menu */
.navbar .nav > li > a:first-letter {
font-size: 16px;
}
