What about having an array of Rune to store worddelimiters and have a
simple search function such as:

Rune *
utf8strchr(Rune *s, Rune u)
        for (; *s; s++)
                if (*s == u)
                        return s;
        return NULL;

The worddelimiters definition will become:

Rune worddelimiters[] = { ' ', 0 };

Which will allow adding unicode codepoint from wide char literal.
Even if the wchar_t is 16 bits wide the constant will be stored
into a Rune, which I belive is a 32 bits constant, and should work
