Hello
Consider please the following example:
| Anton |
| Álvarez |
| Arrieta |
org-table-sort-lines using alphabetic ordering results in
| Anton |
| Arrieta |
| Álvarez |
Which is contra intuitive to say the least. The accented A should be
treated as if it did not have an accent resulting in
| Álvarez |
| Anton |
| Arrieta |
That is the way excel (which I try to avoid usually but which is doing
the right thing), works, libreoffice ooffice is also on the wired side
here.
regards
Uwe Brauer

Alphabetic ordering uses `string-lessp', which doesn't fulfill your
needs here. You can however, sort by an arbitrary function using f or
F key.
In any case, char folding is a complicated matter, because it really
depends on the host language. I think development Emacs provides
something like this.

Which function could you recommend?

I am using GNU emacs 25.1.50 so that requirement is fulfilled. Do you
have any pointers?

I don't know. There may be something readily available in Emacs 25.
Otherwise, you'll have to write you own.

Probably look for "char-fold.el".
Regards.

It seems that the easiest solution is the following
- run iso-unaccentuate (which runs on regions) on the table, which
will change Álvarez to 'Alvarez,
- sort. The sorting is ok
- reconvert via iso-accentuate the table.
I don't understand much of the org-table sort code. My naive approach would be to
define
org-table-iso-accentuate and org-table-iso-unaccentuate and then add
that via defadvice to the original function, but that seems a bad
approach since defacvice makes it difficult to debug.
Any suggestions?
Thanks
