Ok, look carefully:

Why are you setting wordcharacters?

Do you see diseño anywhere?

You can see that diseño is being split into dise and o.  That
indicates that ñ is not in wordcharacters -- regardless of what your
posted config says.

Comment out Wordcharacters.

Also:

Is your input file really encoded in utf-8?  I used iso-8859-1 in my example.

Again, libxml2 parses the input XML file -- and it must know the
correct encoding of your file.  Then libxml2 passes the text to swish
which then converts it to 8859-1.

-T indexed_words shows the words swish indexes after splitting on
Wordcharacters and applying IgnoreFirst/Last and Begin/EndChars.

-T parsed_words will show you the "white-space" delimited words before
Wordcharacters and friends are applied.
