No. [[:word:]] matches characters that have the word syntax, so which
characters match depends on the major mode. My suggestion is to use
either [[:alnum:]] or [[:alpha:]] instead, depending on whether you
want or don't want to match digit characters.
The meaning of each character class is documented in the "Char
Classes" node of the ELisp Reference manual, I suggest to read it and
choose the most appropriate one for your needs.
