Feature description

Hi iOS Team,

there is a forbidden_characters=[....] feature in the WebUI that disallows the usage for renaming/uploading/moving of files & folders with specific characters that are forbidden.
Could we also implement this in the iOS Client so that it is in sync with the frontend?

• fix(files): disallow illegal characters server#40585
• Disallow illegal characters / ? < > \ : * | " and so on in file and folder names server#38614
• [Bug]: 'forbidden_chars' Not Enforced During File Uploads server#43423

Thank you for your effort! :)
