Sorry, I'm juggling a million things at once and have been leaving lots of
little details like this out.

Given the same correct input string, the reordered output string from my
routine should be the same as a true implementation of the Unicode Bidi
algorithm.

The difference with my algorithm is that even if some explicit directional
marks get left out (an incorrect input string, if you will), the text will
probably be reordered correctly anyway.

I definitely agree that there should be a single way to do this.  It makes
life a lot easier for everyone.

About the same amount of code in my routine so far too.

Very likely.
