Strange that we write 0x2030 and not 0x02030 here given the rest of the surrounding code.

This entire function has a coding style that is not great. A whole long data table written out as separate function calls, with no rationale given for the choices of the values or even a summary at the top. Did this come from some table in some specification? Does ICU have a function for this, and if so, why aren’t we using that?

Yes: http://www.unicode.org/reports/tr50/tr50-6.Orientation.txt

The numbers in this function originally came from a giant switch statement; I'm guessing the leading 0s existed to make the case statements right-aligned.

I looked for an ICU function, but couldn't find one. I emailed Kida-san last week to ask if he knows of one.
