[XeTeX] Hyperref \hyperlink and \hypertarget not working with accented characters

[Philip TAYLOR (Webmaster, Ret'd)]

Dear Arthur, Paul, Heiko, Ross, others --

I was serious too (even when speaking of nominating Heiko
for the non-existent position of vice-Grand-Wizard of TeX :
that was a genuine expression of respect for his quite remarkable
solution to the problem of ascertaining whether a given control
word was, or was not, a TeX primitive).  I was also very serious
when I sought to defend the right of someone who wished to use

There is no reason at all why someone using \hyperlink and \hypertarget
should need to know anything about AdobeStandardEncoding, byte strings,
UTF-16, or any of the other deeply technical considerations that
prevent "rAsociación" from being used /directly/ as a Name string;
whatever massaging that is necessary to convert from "rAsociación"
to a derived byte string in AdobeStandardEncoding (or whatever)
should be the responsibility of the intervening software layer
that implements \hyperlink and \hypertarget.  It surely /cannot/
be acceptable in the 21st century to tell such an author "Don't use
non-ASCII characters in the link" unless such a statement is qualified
with the words "until such time as the intervening software layer is
updated to allow such things".

/This/ was the point that I was seeking to make, and if I made it
badly, then I apologise : all messages sent over the last few days have
been sent in conditions of extreme difficulty, with one arm completely
useless (as a result of a tendon injury) and considerable pain (for
the same reason).

Very sincerely :
