@RandyBarry Why are independent numbers transliterated to \u66x but the ones above on lines 107-115 are left unchanged?

Randy's Response:

For Arabic, numerals, cataloging rules are complex for how to treat numerals. In areas like the title where numerals might occur they need to be in the original script but in areas like an edition statement or series volume numbering statement some languages prefer to keep western style numerals. Arabic and Chinese have this kind of exceptional treatment. That’s why you see the special numeral conversion logic for Arabic Roman-to-script.

I'm not sure why all the lines in the file are reported as changed, that's strange. But if it has been tested and works, I guess that's fine.
