So here we arrive. I see two ways to deal with this:
1) *solution* make gitk use IANA names
2) *workaround* get from somewhere the list of Tcl/Tk recognized codec names and
teach qgit to do the map from IANA when setting a codec with "git-repo-config
i18n.commitencoding"
The intent of i18n.commitencoding is to have something that is
understood by iconv there, so if gitk does not work with these
things spelled like. ISO8859-1 or ISO-8859-15, and qgit is happy
with them, I would say that we should fix gitk, which means
*workaround* should be on the tcl/tk side.
Tcl/Tk expert may have more thoughts (and I suspect experiences)
on this, but I am not one of them.
