Wrong Readme.md prohibit folder listing

[francoisvignon]

Hello

If a folder contains a Readme.md file with an accented character (é, è, à ... ) encoded in iso-8859-1 in its content, then the parent folder is not available for the iOs client.

How to reproduce:

• create a folder ‘test’ with two subfolders ‘test/a’ and ‘test/b’:
• on the iOs client, the test folder is displayed correctly and shows folder a and folder b.
• now, put in the folder ‘test/a’ a Readme.md that contains an accented character encoded in “iso 8859-1”:
• now, on the iOs client, the test folder is displayed empty.
• Rename the test/a/Readme.md to test/a/Readme_old.md.
• now, on the iOs client, the test folder displays its two subfolders.

Easy, right? but it took me a long time to find this... after suspecting a long delay (because when I first encountered this failure it was with a big file), optimizing my server, etc. and finally finding it!

I can provide you with some examples.

tested with Nextcloud ios client 6.1.6 and Nextcloud Hub 9 (30.0.2).
