Concat RTL string with LTR string in javascript

Question

I\'m facing trouble in concatenating Arabic string with English string but their order is being messed!

I tried + operator and str1.concat(..)

Answer 1

The characters your are looking for are \u202A, \u202B and \u202C

function wrap_dir(dir, str) {
    if (dir === 'rtl') return '\u202B' + str + '\u202C';
    return '\u202A' + str + '\u202C';
}


wrap_dir('ltr', a) + wrap_dir('ltr', '\\') + wrap_dir('rtl', b) + wrap_dir('ltr', '\\') + wrap_dir('ltr', c);
// "‪english‬‪\‬‫أ.ب-000082-13‬‪\‬‪000004-ر خ-2014.xml‬"

Not sure why c wanted to be LTR, maybe because it ends .xml?
