It can be done with Perl. For example:

$ echo "El castellano es la lengua española oficial del Estado. Las 
demás lenguas españolas serán también oficiales en las respectivas 
Comunidades Autónomas" | perl -M'encoding utf8' -MUnicode::Normalize -pe 
'$_=NFKD($_);s/\pM//og'

The following output should be seen:

El castellano es la lengua espanola oficial del Estado. Las demas 
lenguas espanolas seran tambien oficiales en las respectivas Comunidades 
Autonomas
