I can write Arabic/Urdu/Persian on MS Word or Notepad just fine, but whenever I insert any English word or number, the sequence is just disturbed and seems like the all the words have been shuffled in the sentence.
Look at the example below:
یہ ایک مثال ہے اردو کی ...
Now I inserted an English word and it became:
یہ ایک مثال ہےword اردو کی ...
So you can see almost all of the words have been jumbled ... what is the solution for that ?
For example:
باللغة العربية “keyboard” انا أريد أن أعرف الكلمة
If you're working in Microsoft Office or Open Office, the "special characters" can be found under "insert" [Insert -> symbols -> other symbols -> special characters in MS 2013]. Scroll through until you find the character with the appropriate Unicode number, and if the Unicode number does not appear in your version of MS Word, select it by its name [as indicated above].
You can also add the character by writing it's unicode and then selecting it and pressing Alt+X - but that can be confusing because it needs constant change between Arabic and English.
All of the special characters involved in this little manoeuvre are invisible characters (their job is simply to change the direction of the text) so don't be surprised if it looks like you're not inserting anything.
Pay attention to select the RTL option from the ribbon when the majority of your paragraph is RTL and keep it selected [as shown in the picture in this answer https://stackoverflow.com/a/46050171/8558867 ].
