How to replace the UAE currency symbol to the new symbol, which is the “D” with two horizontal lines. In Magento Backend

How can I use the new UAE Dirham symbol across Magento if it doesn’t yet have a Unicode character and the backend only accepts text (not image or font uploads)?

The Central Bank of the UAE recently introduced a new currency symbol for the Dirham. However, since there’s no official Unicode character for it yet, Magento backend fields like currency symbols only accept plain text—not image uploads or font styling.

I’d like to replace all instances where the currency is currently shown as AED or Dhs with the new symbol. Since I can’t directly insert a font or image in the backend config, is there a core template, layout, or helper file I can override or modify to render an image or custom font instead? Essentially, I want to apply this replacement globally across the site—admin.

Where is the root place (PHTML/template/helper/etc.) that controls how the currency symbol is displayed so I can hook in my image or font workaround?
