I made this regex demo (working) here: <https://regex101.com/r/WSwEbY/6>

When I use it in notepad ++, it doesn't work with multiple lines:

```
hello ladies how are you Today
hello ladies how are you Today

-> result is on a single line:
helloLadiesHowAreYouTodayHelloLadiesHowAreYouToday

```

Informations:

```
search: [^\w]+(\w) 
replaceby: \U$1
n++version: 7.5.8

```

I also try to check 'multiline' or add '$' to en of the search.
