[FEATURE REQUEST] Additional Sort Order setting

[mmattel]

Please describe.
Files shown on IOS devices sorted by name look like this:

1_datei.txt
10_datei.txt
11_datei.txt
2_datei.txt
3_datei.txt

Describe the solution you'd like
The sort order should be additional selectable like this:

1_datei.txt
2_datei.txt
3_datei.txt
10_datei.txt
11_datei.txt

Hm, good point. This is like in macOS Big Sur Finder and iOS 14 Files app.

@hosy @felix-schwarz do you remember why we choose 1_datei.txt, 10_datei.txt, 2_datei.txt ?

Same in oC 10.7 web UI and ownCloud-web:

oC 10.7 web UI	ownCloud-web

I think we should change it.

@mneuwert is this related to “collation”? What spec did we implement? Is there another rule that would be better?

[mneuwert]

@michaelstingl Sorting is implemented in the ownCloudAppShared framework. In case of alphabetic sort, we just use Swift standard library API String.caseInsensitiveCompare(String). Foundation NSString.compare(options:) would allow to tweak comparison algorithm behaviour by applying several available options like:

• ignore diacrtics
• numeric comparison
• etc

There is even quite old dev Q/A from Apple discussing the topic of "comparing files name like in Finder" using CoreFoundation functions:
https://developer.apple.com/library/archive/qa/qa1159/_index.html

To summarise: this would be an easy fix. Just replacing String.caseInsensitiveCompare() with NSString.compare() with few options (numeric, case-insensitive, width-insensitive) would do the job IMHO

Done and released in 11.9
