Hello
We use WHMCS in Arabic.
Arabic is RTL language and it is written from right to left.
When mixing two languages with different directions the result we get is a mess and disordered words and numbers.
For example, we can't do any styling inside {$invoice_html_contents}.
The numbers of the date is mixed up with the numbers of the product cost and so the client can't understand anything.
A partial solution to this problem is to put each element in a class then we can control the format of each element individually and determine its direction.
Thanks
