AHK Hotstring for Multi-language Input

Question

I am bilingual (English and Persian), and I regularly switch between keyboard input languages by pressing Alt + Shift. Since it's not an easy type, I am trying to create a hotstring in Auto Hot Key (AHK) to send Alt + Shift by pressing jf:

:*?:jf::
    SendInput, {AltDown}{Shift}{AltUp}
Return

While this works perfect, I need to press the same keys in Persian language to switch back to English, so I updated the code to:

:*?:jf::
:*?:تب::
    SendInput, {AltDown}{Shift}{AltUp}
Return

Now, the second line doesn't work, and by putting a breakpoint on the SendInput line, pressing those keys in Persian, does not even trigger the hotstring. Any solution? Thanks!

Here are the things I've tried to fix and failed:

• Using Send and SendInput methods
• swapping the order of jf and تب lines
• Compiling the code to see if the .exe works
