There are functions to do this to strings, what comes to mind
is `replace-regexp-in-string', but what difference do you mean
there are between filenames and strings that look like filenames?

To me it would be enough downcase all chars, convert chars
with various decorations to their ASCII base equivalents (e.g.
our Swedish å, ä, and ö to a, a, and o - not that one should
use non-English for filenames so a bad example, but sometimes
English has such chars as well), then use the dash char as the
word delimiter, and after that probably just drop remaining
non-alphanumerics.
