A very simple example, using lower case (!) for RTL:

The logical sentence:
     W3C is written in latin letters in hebrew.
Is displayed as:
     .werbeh ni srettel nital ni nettirw si W3C
The first letter is "W", but it appears in the middle of the line
due to reordering.

Of course. I don't see any problem there; the text is very
careful to always speak of 'first' rather than leftmost or
whatever letter.

I have a vague recollection of Arabic with letters of different size.
I hope somebody can confirm.
There is nothing in principle that would disallow making the first
letter larger (or otherwise different in style) even if the script
is cursive.
