But what does that mean? The w motion recognises å as a
letter, the regex \w does not.

w moves a *word* forward. A word is:

A word consists of a sequence of letters, digits and underscores,
or a sequence of other non-blank characters, separated with white
space (spaces, tabs, <EOL>). This can be changed with the
'iskeyword' option.

My iskeyword setting is:

iskeyword=@,48-57,_,192-255

Why does w move over the word treść? The letters ś and ć are not
considered to be a letter, right? iskeyword lists range 192-255. If
I hit ga on ś and ć, it reports the codes 347 and 263.

\k seems to work. Is it safe to replace all occurrences of \w with
\k? That seems to be the easiest solution. And I still don't
understand *why* it works, since 347 seems to be out of range for
iskeyword.

This works for å and ä but fails on ś and ć.
