I started to look into this as well, but have been working mostly on Unicode
normalization. I probably have some code ready for use in 2-3 weeks. When
normalizing the dn, we should also do Unicode normalization I think.

I know that uppercasing is used now, but I'm wondering if it would be
better to do lowercasing. In most cases there are mostly lower case
characters to begin with (I think).

Do you plan to look at the case where it won't fit later?
I had planned to do what you did later, but I'm glad you did it, then I
can find time for other things (:
