Tags containing umlaut characters not working

- This is not a feature request
- This is not an image-provider request
- I have searched the issuetracker if the issue is not already reported.
Describe the bug:
Images containing umlaut characters (e.g. Ä or Ö) in their tags aren't displaying.
To Reproduce:
Steps to reproduce the behavior:
- Go to Splash settings
- List only tags containing umlaut characters, for example jönköping, hämeenlinna, jyväskylä
- Refresh the page, and an error background image is displayed.
Expected behavior:
Images containing these tags should appear.
Server:
- Nextcloud version: 27.0.1
- Splash-App version: 2.2.1
Additional Information:
- The bug can be circumvented by omitting the umlauts, i.e. "jonkoping, hameenlinna, jyvaskyla".
- It looks like some tags containing umlauts DO display other images besides the error image, such as öland and häme. Note, however, that the tag häme only displays an image of a cat, completely different from the 23 images that you can find, if you use the same tag at unsplash.com.
- I also tried adding cyrillic tags, such as Москва, and it seemed to work.
Line 116 in lib/ProviderHandler/Provider.php is responsible for that behaviour
$term = preg_replace('/[^a-z]/i','', $term);
does not only affect umlauts, but basically any character that is not in the range U+0061 to U+007A (standard latin lowercase letters)
I also tried adding cyrillic tags, such as Москва, and it seemed to work.
that's because it results in an empty search string, so you just got a completely random image, not necessarily with any relation to moscow
I'm taking the comment line // only allow letters as searchterm
as that it was a design choice with a rationale.
