Okay, I am using this version. I was just a little confused
about how to specify a character set that comprised as many
characters as possible. But from what you say, it seems that I
can just do

   define_syntax ("a-zA-Z", 'w', "tbl");

and still have all non-ascii characters covered? I just tried
with some non-ascii latin characters and indeed it seems to
work that way.

I think it works very well.

It is a spell checking function that highlights misspelled word
that I am working on.

I will surely test this also.
