Issue with Arabic and Mixed-Language Subject Line Rendering in AJO

I am working on configuring an Arabic subject line for an email in Adobe Journey Optimizer (AJO). When I copy and paste the subject line into the AJO subject field, it does not render correctly and the text order appears altered. The subject line includes a combination of Arabic and English text, numbers, and an emoji/icon. I have attempted to resolve the issue by using HTML and JSON code to enforce right-to-left (RTL) formatting, but these methods have not been effective.
Has anyone experienced a similar issue or found a solution for ensuring proper RTL rendering in AJO subject lines that contain mixed languages and symbols? Any guidance would be appreciated.
