It may be a red herring, but I seem to remember Mac choosing to go with
what is now a non-standard normalization form (NFD), vs.
linux, windows and the web going with NFC.

In computing char lengths it might be the case that something is
converting characters to a normalized form and maybe the gnu
code uses the more standard form,  and somewhere text is being
forced through 1 or more normalization transforms?

It may be a non-issue, but was something that occurred to me
as problematic should text between platforms be shared and run
through text processors that want a native normalization form.
