cw, dw, vw doesn't work with non-ascii char earlier in line

[Tobbe]

Describe the bug
cw, dw, vw etc changes/deletes/selects more than the expected word when there's a "special" character earlier on the line

To Reproduce
Paste the following line in a new file

expect(foo('£')).to.equal('p');
                           ^

In normal mode, place the cursor on p (as indicated by ^ above)

type dw

The line is now

expect(foo('£')).to.equal('
                          ^

Expected behavior

The line should be

expect(foo('£')).to.equal('');
                           ^

Screenshots

First, with £ earlier on the line dw deletes to the end of the line (this is the bug)
Chainging £ to g dw only deletes the p, as expected

The cause of this issue is due to mishandling of Latin-1 symbols (e.g., '£' and '©'). It seems that characters after a Latin-1 symbol are wrongly regarded as a single word.

I rewrote the word separation part in the recent PR (#3667) a week ago, and it happened to fix the problem you mentioned. However, I found that there is another problem in terms of Latin-1 symbols so that I made additional changes to the PR.

Thanks for reporting the issue!
