I agree with all of your remarks.

I have been also amazed by the fact that my patch_accent
was not totally corrupting de db file ;)

Looks like, ASCII codes modified are not used as separators and attributes.
Please note I took care of only modifying bytes that were in an ASCII
string :)

In fact I just have written this patch to match my purposes.

I made it public because after searching "accents french"
on the htdig site, I found a huge numbers of people trying
to get a solution ....

Don't be wrong, this patch is not an academic one,
it is a dirty and straightforward one (as I said on my page).

My point of vue, of a *good* patch is something like a conf file, let's
call it transcode.conf
which would contains characters equivalences.
this file would be used by htsearch and htfuzzy.
