<div style="font-family: Raleway;">The approach differs not only
by script and which digits are used, but also by language.
Arabic and Persian both use the Arabic script, but do things
differently when it comes to ordering components of a range or
expression.<br>

<p>Isn't that difference handled by having two different sets of
digits? As opposed to relying on a language tag.<br>

Also, we should probably mention that some scripts don't display
simple numbers like Arabic/Hebrew, either. For example, in Adlam
& N'Ko and various historical scripts numbers have the
most-significant digit on the right.<br>

While Arabic and Hebrew agree on the same ordering of
digits, with the most-significant digit on the left, the
layout of entire numbers in context, including groups of
numbers or use of number separators, numerical and other
punctuation differs both by script and, in the case of
Arabic, by which set of digits is used. No matter how the
layout is resolved the order of characters in
memory essentially follows the order they are typed. <br>
