Looking at the source for gsort reveals that it's mostly engaged in macro
manipulation with an occasional call to sort to do the basic work. Since sort
itself is a built-in command, it would almost HAVE to be Stata that made any
such modification.

Quoting John LeBlanc <[email protected]>:
Thanks; I was hoping that Stata had a built-in option to ignore
accents. Some software with sort routines have the ability to give
characters with diacritical marks the same value as their own. Is
this not an issue for non-English Stata users? Is there sufficient
desire to justify asking stata for this feature, e.g., as an option
to gsort?

How does one ignore accents while sorting international characters?
sort & gsort deliver this:
ecole
school
�cole
What I'd like is this:
ecole
�cole
school
============================================================
I believe that you must generate a second variable with no accents
to get it right:
gen str10 key2=key
replace key2 = subinstr(key2,"�","e",.)
replace key2 = subinstr(key2,"�","o",.)
...
sort key2 key
I included key as a secondary sort key to make � come after e.
Hope this helps
